Question

The measure of ∠1 is 70°. Find m∠2 and m∠3.

Answer 1

Answer

Step-by-step explanation:

3). m∠1 = 180° - 98° = 82°

m∠7 = 180° - ( 98° + 23° ) = 59°

m∠6 = 180° - ( 70° + 59° ) = 51°

m∠9 = m∠6 = 51°

m∠10 = 180° - 51° = 129°

m∠4 = 180° - ( 70° + 51° ) = 59°

m∠54 = 180° - (23° + 59° ) = 98°

4). m∠1 = m∠4 = m∠11 = m∠13 = 90° - 54° = 36°

m∠2 = m∠5 = 90°

m∠6 = m∠3 = m∠8 = m∠10 = 54°

m∠7 = m∠9 = 90° + 36° = 126°

m∠12 = m∠14 = 180° - 36° = 144°
