Answer:
Step-by-step explanation:
Use ratios to find x and y, then find AB and GH, them sum up the lengths.
<u>Find x:</u>
- 12/15 = x/10
- x = 12*10/15
- x = 8 in
<u>Find y:</u>
- 12/15 = 16/y
- y = 15*16/12
- y = 20 in
<u>Find AB:</u>
<u>Find GH:</u>
<u>Find the perimeter:</u>
- P = 6 + 15 + 20 + 10 + 37 + 8 + 16 + 12 = 124 in

Step-by-step explanation:
Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
Answer:
a) well we know the hypotenuse and we know that all sides are 90 degrees, and that its an even square, so if we split it into a triangle , we know that the other 2 angles are 45 degrees total, with this we can calculate the other 2 sides, which round to 10 inches.
b) if we know the sides of the first side, knowing the fact that its a square we know that all sides are even, therefore, all sides are 10 inches, the formula the finding the perimeter is basic:
P=L(2) + W(2)
L being length, W being width and P being perimeter
so we add up all 4 sides, here is the equation:
10 + 10 + 10 + 10 = 10 x 4 = 40
With this, we know that the perimeter is 40 inches total
c) knowing how long the sides are, we can figure out the area through another basic formula:
A=L X W
With A meaning Area
since its a square, we know all the sides are even, so the width and length are both 10...
10 X 10 = 100
