Question

Find the parallelograms please​

Answer 1

a = 45°, x = 90°

Explanation:

2a + x + 2a + x = 360°

2a = x because they are the same two angles. 2 out of 4 angles = 1/2. 1/2 x 360° = 180°

2a + x = 180°

Since 2a = x, that means x has to equal to 90 and 2a has to also equal to 90

180°/2 = 90°

x = 90

2a = 90

2a/2 = 90/2

a = 45°

2(45) + 90 = 180°

90 + 90 = 180

180 = 180
