The measures of two adjacent angles of a parallelogram are in the ratio 3:2. Find the measure of each of the angles of the parallelogram.
Answers
Answer:
Let the measures of two adjacent angles, ∠A and ∠B, of parallelogram ABCD are in the ratio of 3:2.
Let ∠A = 3x and ∠B = 2x
We know that the sum of the measures of adjacent angles is 180º for a parallelogram.
∠A + ∠B = 180º
3x + 2x = 180º
5x = 180º
∠A = ∠C = 3x = 108º (Opposite angles)
∠B = ∠D = 2x = 72º (Opposite angles)
Thus, the measures of the angles of the parallelogram are 108º, 72º, 108º, and 72º
Step-by-step explanation:
Let us take the two adjacent angles be 3x & 2x
Note :- Sum of the adjacent angles in a parallelogram is 180°
So, we will simply add up and equal to 180 and will get the value of x
→ 3x + 2x = 180
→ 5x = 180
→ x = 180/5
→ x = 36
Thus, we got the value of x which is 36
Now, we will simply subsitute the values
1st angle :- 3x = 3 × 36 = 108
2nd angle :- 2x = 2 × 36 = 72
