Please help first good answer will be marked the brainiest

x = 5

Step-by-step explanation:

The measure of an inscribed angle is 1/2 the measure of the intercepted arc.

∠X is an inscribed angle and arc QRS is its intercepted arc.

arc QRC has a measure of 122 + 76 = 198

Therefore, m∠X = 1/2(198) = 96

So, 19x + 1 = 96

19x = 95

x = 5

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°

the answer is d
