1. Decide whether the statement below is true or false. Then fully explain why. The triangle below can b used to help with your explanation if needed. "The sine of any acute angle is equal to the cosine of its complementary angle."[help me plzz!!]​

Work Shown:

sin(angle) = opposite/hypotenuse

sin(alpha) = MN/NP

sin(alpha) = y/z

cos(angle) = adjacent/hypotenuse

cos(beta) = MN/NP

cos(beta) = y/z

Both sin(alpha) and cos(beta) are equal to y/z, so that means sin(alpha) = cos(beta). This is true because alpha+beta = 90, ie the angles are complementary.

Similarly, you should find that sin(beta) and cos(alpha) are both equal to x/z, which is further proof that the statement is true.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
