Question

Can u pls solve this question

Answer 1

Answer:

Step-by-step explanation:

Consider triangle ABC,

<BAC + <ABC + <5 = 180

<5 = 180 - (60+30) = 90.

<5 + <1 = 180

<1 = 180-90 = 90

Consider triangle with angles 3, 1 and 4.

<1+ < 3+ <4 = 180

<1+ < 3+ < 3 = 180 (<4=< 3)

2× < 3 = 180 - 90 = 90

< 3 = 90/2 = 45

< 3 = < 4 = 45

< 2 = < 1 + < 4 (measure of exterior angle equal to sum of

opposite interior angles)

< 2 = 90 + 45 = 135.

Answer 2

Heya!!

here is your answer✌

angle A + B + 5 = 180°

30°+60°+ 5 = 180°

angle 5 = 180°-90°

angle 5= 90

Angle 5 + 1 = 180° (linear pair)

90° + angle1 = 180°

angle 1 = 180°-90°

angle 1 = 90°

angle 3 + 4 + 1 = 180°

2(angle 3) + 90° =180°{3=4)

angle 3 = angle 4 =45°

angle 2+3= 180° {linear pair)

angle 2 + 45° =180°

angle 2 = 180° - 45°

angle 2 = 135°
