Question

Maths
Find x In the following Figures given Below....
No Timepass Please
Write Answer with a proper Explanation..​

Answer 1

Answer:

i)

x + 3x = 180° ( interior angle)

therefore 4x =180

x = 180 / 4

x = 45°

ii)

3x = 90° (corresponding angles)

iii)

2x+15 = angle E ( vertically opposite angle)

angle E + (x + 15) = 180° ( interior angle)

2x+15+x+15 = 180

3x + 30 = 180

x = 210/3

x = 70

Answer 2

Answer:

(i) x=45°, (ii) x=30°, x=50°

Step-by-step explanation:

In (i) AB||CD, so x+ BAL=180° (Linear pair)

BAL = 3x (Corresponding angles)

Therefore , x+3x=180°

4x=180°

x=45°

In (ii) PQ||RS , therefore 3x=90° (Corresponding angles)

x=30°

In (iii) PQ||RS, RFE+x+15°=180°

RFE= 2x+15° (Corresponding angles)

so, x+15°+2x+15°=180°

3x=150°

x=50°
