Answer:

∠ A = 60°

Step-by-step explanation:

Consecutive angles in a parallelogram sum to 180° , then

∠ A + ∠ B = 180° ( substitute ∠ B = 2 ∠ A )

∠ A + 2 ∠ A = 180°

3 ∠ A = 180° ( divide both sides by 3 )

∠ A = 60°

Triangle TRS is similar to triangle TMN. Angle T = 40°, angle R = 60°, and angle S = 80° . What is the measure of angle M
Andre45 [30]

Answer:

60degrees

Step-by-step explanation:

For similar triangles, the angles of their angles are equal to matter the size.

Hence if triangle TRS is similar to triangle TMN, then;

<R = <M and <S = <N

Given that;

<T = 40 degrees

<R = 60degrees

<S = 80 degrees

Since <R = <M, then <M = 60degrees
