What are the missing angle measures in parallelogram
rstu?
a. mzr = 70°, mt = 110°, mzu = 110°
b. mzr = 110°, m_t = 110°, m_u = 70°
c. mzr = 110°, m_t = 70°, m_u = 110°
d. mzr = 70°, mzt = 110°, m_u = 70°

Check the picture below.

let's recall that in a parallelogram, opposite angles are congruent and angles on the same segment are supplementary.

it is a secret for it not to be compromised sorry

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
