Question

17. In a parallelogram ABCD, the measure of angle A is three times the measure of angle B. Find all the four angles .​

Answer 1

Answer:

45° is answer please mark me branliest

Step-by-step explanation:

So, the measure of Angle A be '3x'. Since ABCD is a parallelogram, so the measure of opposite angle is equal and consecutive angles are supplementary. On putting the values, we get; Hence The measure of ∠A, ∠B, ∠C and ∠D are 135°, 45°, 135° and 45° respectively.
