Question

27. In triangel ABC, angel A+ angel B=110, angel C + angel A = 135º. Find angel A.​

Answer 1

Answer:

Step-by-step explanation:

Angle A + B+ C= 180

110+C=180

C=180-110

C=70

A+B+C=180

135+B=180

B=180-135

B=45

A+ B+ C =180

A+45+70=180

A+115=180

A=180-115

A=65

Hope it helps

Answer 2

Answer:

65

Step-by-step explanation:

sum of the interior angles of a triangle=180°

i.e. angle A+angle B+angle C =180°

110°+C=180°

C=180-110=70°

THEN,

angle A+angle C=135°(given)

angle A+70=135°

angle A =65°
