Question

Please help me in this question

Answer 1

Step-by-step explanation:

i) x= 360°—(41°+105°+130°)

= 360°—276°

=84°

ii)3x+x+40°=180°

or, 4x=180°—40°

or, x=140°/4

=35°

iii)(2x+10°)+(3x-10°)+40°=180°

or, 5x=180°—40°

or,x=140°/5

=28°

Answer 2

Answer:

Angles in linear pair are supplementary.

(2)

3x + x + 40 = 180

4x +40=180

4x= 180 -40

4x = 140

x=140/4

x= 35

3x = 3×35= 105

(3)

2x+10+3x-10+40=180

2x+3x+10+40-10=180

5x+40=180

5x=180-40

5x=140

x=140/5

x=28
