Question

If angle 1 is equal to angle 2 and and 3 is equal to 76 degrees, find the measure of angle 1 and angle 2

Answer 1

Answer:

52 degree

Step-by-step explanation:

let angle 1 and angle 2 to be x

so, angle 1+ angle 2+ angle 3= 180

2x + 76= 180

2x=104

x=52

hence proved

Answer 2

Answer:

$Given:\:\angle \: 1 = \angle \: 2 \: and \:\angle \: 3 = 76 \degree \\ \because \angle \: 1 + \angle \: 2 + \angle \: 3 = 180 \degree \\ \therefore \: \angle \: 1 + \angle \: 2 + 76 \degree = 180 \degree \\ \angle \: 1 + \angle \: 2 = 180 \degree \: - 76 \degree \\ \angle1 + \angle \: 2 = 104 \degree\\ \: \\ \angle1 + \angle \: 1 = 104 \degree( \because \: \angle \: 1 = \angle \:2) \\ 2\angle \: 1 = 104 \degree \\ \angle \: 1 = \frac{104 \degree}{2} \\ \angle \: 1 = 52 \degree \\ \implies \: \angle \: 2 = 52 \degree$
