Find the missing side lengths for the following right triangles,

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

For a function f(x), a) if f(7) = 22 then f^-1(22) = b) f^-1(f(c)) =
