Answer:
17
Step-by-step explanation:
First of all, based on the Pythagorean theorem, a^2 + b^2 = c^2
(it's very important that the ∠ABD angle is 90 degrees)
8^2 + 15^2 = s and 5^2 + 15^2 = CD (but the original question doesn't want the value of CD, so we just need to solve for s)
64 + 225 = 289 now remember, 289 is s^2, and we only want the value of s, so we have to find its square root: √289 = 17

Answer: The value of x is 3.
Step-by-step explanation:
so we know the surface area of the shape as 112.
And to find the missing angle we could use the equation
20 + 20 + (10 *x) + ( 10* x) +(2 * x) + (2 * x) =112 solve for x and that is x
20 + 20 + 10x + 10x + 2x + 2x = 112
40 + 24x = 112
-40 -40
24x = 72
x= 3
Check: 3 * 10 = 30
3 * 10 = 30
2 * 3 = 6
2 * 3 = 6
2 * 10 = 20
2* 10 = 20
30 + 30 + 6 + 6 +20 +20 = 112
112 = 112
