Question

Please tell answer I will mark as brainliest please bata do yaar kal exam hai​

Answer 1

Answer:

I) 84 °

it was a reflex angle =360°

therefore , 41°+ 105° + 130° + x = 360°

276+ x = 360°

x = 360° -- 276

x = 84°

ii) 3x + x + 40 ° = 180°. ( linear pair )

4x + 40° = 180° ( """ )

4x = 180° -- 40°

x = 140° ÷ 4

x= 35 °

iii) 2x + 10 ° + 3x -- 10° +40 ° = 180° (linear pair )

5x + 40 = 180 ° ( +10 -- 10 get cancelled )

5x = 180°-- 40°

x = 140°÷ 5

x = 28 °

Answer 2

Step-by-step explanation:

Answer

1) The whole is complete angle, so

x+41°+105°+130°=360°

= x+276= 360°

=>x= 360-276

=>x= 84°

2) The whole is straight angle, so

x+3x+40°=180°

=> 4x= 180-40

=> 4x= 140

=> x= 140/4

=>x= 35°

3) The whole is straight angle, so

2x+10+3x+10+40=180°

=> 5x+60=180

=> 5x=180-60

=>5x= 120

=>x=120/5

=>x= 24°

Hope this helps you
