divide the shape into 2 triangles and 1 rectangle
left triangle :
hypotenuse = 7 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 7² - 6² )
x = √13
x = 3.6 in
find it's area
6 × 3.6 ÷ 2 = 10.8
right triangle :
hypotenuse = 9 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 9² - 6² )
x = √45
x = 6.7 in
find area
9 × 6.7 ÷ 2 = 30.15 in
middle rectangle :
16 in - left tri. base = base
16 - 3.6 = 12.4
find area
6 × 12.4 = 74.4
sum of the area
10.8 + 30.15 + 74.4 = 115.35
Answer:
1. -5y + 2y = -3y
2. -8r - 16 + 6r - 12
3. -8r - -16 + 6r - 12
4. -8r - -16 + 6r - 12
5. 2m +13
Step-by-step explanation:
why is there 2 of the same
Answer:
<h2>cos 60 = sin30 = 1/2 </h2>

Answer:
486
Step-by-step explanation:
It will be the third one I think because that on is 486 and it seems ro be the correct answer since the sides are nine. Good luck!
