Related angle is 45 degrees, set up a triangle and use exact trig values to solve for x and y, then rationalise the denominators
distribution (if we are talking about algebraic properties)
Answers:
1. V=triangle area × length
V=1/2×8×12×20
V=960in³
2. triangle area × length
Area of the triangle=1/2×4×11
A=22ft²
V=22×6
V=132ft³
3. b, volume always have cubic power (³)
4. d, same reason of question 3
