<YWX=30°; YX=80÷2=40
WX²+40²=80²
WX²=6,400-1,600
WX=√4,800=√(4×4×4×25×3)=40√3
Answer:
40 in²
Step-by-step explanation:
Surface area = 4 triangles + square
= 4[½ × 4 × 3] + 4²
= 4(6) + 16
= 40 in²

14x + -21xy
Factor out the Greatest Common Factor (GCF), '7x'.
7x(2 + -3y)
Final result:
7x(2 + -3y)

Answer:
a=169 ft
Step-by-step explanation:
Here you are given the angle 25, and the opposite and hypotenuse values.
Opposite/Hypotenuse: the sin(angle 25)=a/400ft.
We need to solve for a, so lets multiply 400 to the other side:
400(sin25)=a. Plug this into your calculator and you will get the answer: a=169.04 ft
