Find the indicated side of the triangle.
Answer:
Step-by-step explanation:
Because a and b are both opposite 45 degree angles, a=b. Using the Pythagorean Theorem we can say.
[tex]2a^2=28^2\\ \\ 2a^2=784\\ \\ a^2=\frac{784}{2}\\ \\ a=\sqrt{\frac{784}{2}}\\ \\ a=\frac{28}{\sqrt{2}}[/tex]
9514 1404 393
Answer:
a = b = 28/√2
Step-by-step explanation:
The ratios of side lengths in an isosceles right triangle are ...
1 : 1 : √2 = a : b : 28
If we multiply the first ratio numbers by 28/√2, we get ...
1 : 1 : √2 = (28/√2) : (28/√2) : 28
That is, ...
a = b = 28/√2
_____
Alternate solution
Once you realize the triangle is isosceles, so that a=b, then you can use the Pythagorean theorem.
a^2 + a^2 = 28^2
2a^2 = 28^2 . . . . . . simplify
a√2 = 28 . . . . . take the positive square root
a = b = 28/√2

5m - 2n=4
m - 4n = -1
20 3x + 5y = 11
2x - y=3
Answer:
Step-by-step explanation:
5m - 2n = 4
m - 4n = -1 add 4n to both sides m - 4n + 4n = 4n - 1
m = 4n - 1 now substitute for m into the first equation
5(4n -1) - 2n = 4
20n - 5 - 2n = 4 combine the n coeffients and add 5 to both sides
18n - 5 = 4 + 5
18n = 9 solve for n by dividing 18 by both sides
18 n/18 = 9 /18
n = 1/2 now find for m using m = 4n - 1 m = 4(1/2) - 1 m = 2 -1 = 1
m = 1 (1, 1/2) solves the two equations
3x + 5y = 11 equation 1
2x - y = 3 multiply both sides by 5 so when you add the two equation
the y term is eliminated (becomes zero)
5(2x-y) = 5(3)
10x - 5y = 15 equation 2 add equation 1 and equation 2
3x + 5y = 11 add the like terms
10x - 5y = 15 add the like terms
(3x + 10x) + (5y - 5y) = (11 + 15)
13x + 0 = 26 the y tern is gone now solve for x
13x = 26
13x/13 = 26/13
x = 2 now find y using 2x - y = 3
2x - y = 3 add y and subtract 3 from both sides
2x - y + (y - 3) = 3 + (y - 3)
2x - 3 = y we already know x = 2
2(2) - 3 = y
4 - 3 = y
1 = y answer (2,1) solves the two equaitons

5 Select the correct text in the passage. Which sentence best gets across the author's message in the story? A True Victory Kelso and his best friend, Adiel, had spent weeks building their go-cart for the annual Wolf Club go-cart race. Then, at the last minute, another team's go-cart broke down. Adiel and Kelso decided to let that team use their go-cart. But now they were regretting their decision. It was painful watching the race from the sidelines. When the first cart crossed the line, Adiel and Kelso couldn't helping wydering how it would have felt If they had won. Within seconds, other carts raced by. Instead of feeling glum, Kelso began to laugh. He delighted in the breeze that blew through his hair as the go-karts rushed past. Adiel noticed a genuine smile spread wide across Kelso's face. Adiel realized that this sense of happiness was also surging throughout his body, even though he had not raced. "You did a really nice thing today," whispered a nearby Wolf Club leader. "Thanks," said Adlel. "I guess I won't ever know if I could've won the race." "Well winning isn't one of the Wolf Club mottos," said the leader. "But we do believe that we should promise to do our best and do something good for somebody every day. I'd say you proved yourself today as one of the worthiest people here to be called a Wolf Cub." Adiel's mother soon appeared. "And I'm more proud of you now than I ever could have been if you had come in first," she said. Reset Next n. All rights reserved.

Option 1 : x=2
Option 2 : x=-7
Option 3 : y=2
Option 4 : y=-7
Answer:
Option 1
Step-by-step explanation:
First we need to analyse the question to figure out what we need to do. The question is saying that a line is parallel to the y-axis. We know that the y-axis goes up and down, meaning that our line should be pointing up and down crossing the point (2,-7). In order to find where the line is placed, we would have to look at the x-axis to figure out where it is. Using the info provided we could see that the line has to pass (2,-7), and the x for that point is 2. Using all the info we have concluded we know that the equation of the line is x=2.

A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30 mg. How many milligrams of the vitamin are in the drink?
Answer:
39 mg
Step-by-step explanation:
To get the number of milligrams, all we have to do is to find 130% of the RDA
mathematically, we have this as;
130% of 30
= 130/100 * 30 = 39 mg

Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°
