Answer:
x = 79
Step-by-step explanation:
All triangles have a sum of 180°. Knowing this, we can solve for the unknown angle.
56 + 23 + ? = 180
79 + ? = 180
? = 101
The variable x is known as an exterior angle. That and the angle we just solved for are supplementary meaning they add up to 180°.
101 + x = 180
x = 79
Answer: 18.75 lb.ft
Step-by-step explanation:
Given
Force required to stretch spring 8 in. is 18 lb
it can be written

Work done in stretching from its natural length to 10 in.

I can help you out, 8+10 x Square root of 2 is 22.1421356237 and then you simply take that and multiply it by 90* and y by 30* and i believe you have to use the Sin function on a calculator so
Sin90 X Sin 30
22.14 X Y
Cross multiply
Does the answer require only an exponent?
