Which statement can be concluded using the true statements shown? If two angles in a triangle measure and x degrees, then the third angle measures (90 − x) degrees.

In triangle ABC, angle A measures 90 degrees and angle B measures.

Angle C must measure 50 degrees.
Angle C must measure 40 degrees.
Angle C must measure (90 − 40) degrees.
Angle C must measure (90 − 30) degrees.

answer: do we write it

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
