I need help with this question asap please

y = 3

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

= ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = = = × = 3

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
