Answer:
I think it's D
Step-by-step explanation:
Supplementary means the angels add up to 180 degrees. So 95 + ? = 180. The ? is equal to 85, but how do you get it. Well we know 5x means to multiply a # by 5. So 17 x 5 = 85. So x = 17. Hope this helps!
Hey there! :)
You have to find the area of all of them and add it together.
Formulas:
Area of a square: l · w
Area of a triangle: (b · h) ÷ 2
Square -
l = 3
w = 3
3 × 3 = 9
Triangle -
b = 3
h = 3
(3 × 3) ÷ 2
9 ÷ 2 = 4.5
There are 4 triangles
4.5 × 4 = 18
9 + 18 = 27
The surface area ⇒ 27 cm²
