Step-by-step explanation:
1. I can't see the first one very well.
2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]
3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.
We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'
Work out the area by doing 1/2(2+6)4 = 16' squared.
4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.
To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.
The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer:
y=x+600
Step-by-step explanation:
Hey There!
Slope intercept form is y=mx+b
where m = slope and b = y intercept
slope is change in y over change in x
as y goes up 200 x goes up 200 so the slope is 200/200 or just 1
The y intercept is at (0,600) so the y intercept is 600 now we just put everything together and get that the equation is
y=x+600
What number is in the ten-thousandths spot of pi?
Answers
Answer:To figure out the value you have to look at all of the numbers from right to left. You start with the ones place and get prgressively bigger going up by a multiple of 10 each time. So you have the ones, tens, hundreds, thousands, ten thousands, etc. In the number in your example, you have 3 ones, 4 tens (or 40), 1 hundred or (100), 0 thousands, and 5 ten thousands (50, 000). You can write the number in expanded form to help you figure out the value. 50,000 + 100 + 40 +3.

y=6x-11
-2x-3y=-7
find the solution
Answers
Answer:
x = 13/8
y = 5/4
Step-by-step explanation:
y = 6x - 11
-2x - 3y = -7
6x - y = 11
-2x - 3y = -7
18x - 3y = 33
-2x - 3y = -7
16x = 26
x = 26/16 = 13/8
y = 39/4 - 11 = 5/4
y=6x-11
-2x-3y=-7
The solution to the system of equations is:

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 23cm and a second side that is 4cm less than twice the third side, what are the possible lengths for the second and third sides?
Answers
Answer:
21 < x < 27
Step-by-step explanation:
Given that :
Side 1 = 23
Side 3 = x
Side 2 = 2x - 4
23 + x > 2x - 4
Collect like terms
x - 2x > - 4-23
-x > - 27
x < 27
Also ;
23 + 2x - 4 > x
23 - 4 > x - 2x
21 > - x
-21 < x
x > - 21
Hence,
Possible values of x :
x > 21 and x < 27
21 < x < 27

The given trianagle FAN is an acute triangle.
Step-by-step explanation:
There are three types of triangles on the basis of angle:
Acute triangle: All three angles are less than 90°Obtuse triangle: One out of three angles is greater than 90°.Right-angled triangle: One of the measurements of an angle will be equal to 90°.(As shown in image attached)
Given:
A triangle FAN with an angle measurement of each angke.
To find:
The name adjoining triangle FAN on the basis of angle.
Solution:
In ΔFAN
∠A=55°, ∠F=85° ,and ∠C=45°
∠A<90°, ∠F<90° ,and ∠C<90°
All the given three angles of triangle FAN are less than 90°, which imolies that the given trianagle FAN is an acute triangle.
