If ∆TIK ≅ ∆TOK and < I = (5x + 8), < K = 92, and < O is 50. What is the measure of < I?
Answers
Answer:
<I = 50
Step-by-step explanation:
Sum of angles in ∆TOK is 180
Given
< I = (5x + 8),
< K = 92, and
< O is 50.
<T + <O+<K = 180
<T +92+50 = 180
<T + 142 = 180
<T = 180-142
<T = 38
Also <T+<I+<K = 180
38+5x+8+92 = 180
5x+138 = 180
5x = 42
x = 42/5
x = 8.4
Since <I = 5x+8
<I = 5(8.4)+8
<I = 42 + 8
<I = 50

3x+ 2y= 14 4x- 2y= 16 Elimination.
Answers
3x+2y=14
+4x-2y=16
——————
2y+(-2y) will cancel out leaving you with:
7x=30
Divide by seven to get x by itself, you will get:
x=5
Now plug that in to 4x-2y=16
4(5)-2y=16
20-2y=16
Minus 20 on both sides
-2y=16
Divide by -2 to get y by itself
y=8
Thus,
x=5 and y=8

Find the slope of the line that passes through the points. (10,8) and (4,12) is as a simplified fraction
Answers
Answer:
- 2/3
Step-by-step explanation:
Slope m = (y2-y1) / (x2-x1)
= (12-8) / (4-10)
= 4 / (-6)
= - 2/3
The slope as a simplified fraction is : - [tex]\frac{-2}{3}[/tex]
Meaning of slope
Slope or gradient is the degree of steepness of a line.It is the ratio of the chance in the y- coordinates to the change in the x-coordinates of a line.
m( slope) = [tex]\frac{y2-y1}{x2-x1}[/tex]
Given data
x1 = 10, x2 = 4, y1 = 8, y2 = 12
Therefore the slope can be calculated as :
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
m = [tex]\frac{12-8}{4-10}[/tex] = -4/6 = -2/3
In conclusion the slope of the points (10,8) and (4,12) as a simplified fraction is -2/3

A circle has a diameter of 10 cm a square has a side length of 6 cm use Pythagoras Theorem to show that the square will fit inside the circle without touching the edge of the circle
Answers
Given:
Diameter of circle = 10 cm
Side length of square = 6 cm.
To show:
That the square will fit inside the circle without touching the edge of the circle.
Solution:
A square will fit inside the circle without touching the edge of the circle if the diagonal of the square is less than the diameter of the circle.
We have,
Side length of square = 6 cm.
Using Pythagoras theorem, the diagonal of the square is
[tex]Hypotenuse^2=perpendicular^2+base^2[/tex]
[tex]d^2=a^2+a^2[/tex]
[tex]d^2=2a^2[/tex]
Taking square root on both sides.
[tex]d=\sqrt{2a^2}[/tex]
[tex]d=a\sqrt{2}[/tex]
Putting a=6, we get
[tex]d=6\sqrt{2}[/tex]
[tex]d=6(1.414)[/tex]
[tex]d=8.484<10[/tex]
Since, the diagonal of the square is less than the diameter of the circle, therefore the square will fit inside the circle without touching the edge of the circle.
Hence proved.

Answers
Answer:
-1350 is the answer.
Step-by-step explanation:
The value of multiplication of 25 and -54 will be -1350/1.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression as;
25 × -54
Now. Solve the expression as;
25 × -54 = - 1350
It can be written as a fraction;
- 1350 = -13500/10
