We are given a rain gutter made from folding a 12 inch wide aluminum sheet to an angle theta. The area of the opening is expressed as A(Θ) = 16 sin Θ (cos Θ + 1) where <span>Θ = 45°. we can just substitute directly the angle in degrees mode in the calculator and the answer is equal to 19.32 inches2.</span>
Answer:
B) x=64, y=21, z=64
Step-by-step explanation:
X=180-116=64
Y cannot equal 115, and one angle is already 95, and that would put it over 180. The only remaining choice for y=21
z=180-95-21=64
