Question

pls calculate and write detailed answer for all the questionbs

Answer 1

Answer:

a) sum of the three angles =180°

angle x +55°+45°=180°

angle x +100°+180°

angle x=180°-100°

angle x =80°

b) sum of opposite interior angle = exterior angle

32°+x=108°

x= 108°-32°

x=76°

c) exterior angle =sum of opposite interior angles

x=90°+34°

×=124°

Answer 2

Answer:

a) x=100°

b) x=76°

C) x= 56°

Explanation:

a) and b) are based on exterior angle property.

Exterior angle property : An exterior angle of triangle is equal to the sum of its two opposite non-adjacent interrior angles.

c) is based on Sum of all angles of triangle is equal to 180°.
