Question

In the following figures, find x​

Answer 1

Answer:

Mark as brainliest answer.

Step-by-step explanation:

(i) We know that V.O.A (vertically opposite angles) are equal.

→ 115° = 2x - 25°

→ 2x - 25° = 115°

→ 2x = 115 + 25

→ 2x = 140°

→ x = 140/2

→ x = 70°

(ii) We know that sum of a straight angle is 180°

→ 2x - 5 + 3x + 10 = 180

→ 2x + 3x - 5 + 10 = 180

→ 5x + 5 = 180

→ 5x = 180 - 5

→ 5x = 175

→ x = 175/5

→ x = 35

(iii) We know that sum of a straight angle is 180°

→ 25 + x + 40 = 180

→ 65 + x = 180

→ x = 180 - 65

→ x = 115°

Answer 2

Step-by-step explanation:

We know that V.O.A (vertically opposite angles) are equal.

115° 2x 25

2x 25° 115

2x 115+25

2x = 1400°

X 140/2

X= 700°

(i) We know that sum of a straight angle is 180

2x-5 + 3x +10 180

2x+3x - 5+10 = 180

5x+5 = 180

5x 180 - 5

5x 175

x= 175/5

X= 35

(i) We know that sum of a straight angle

is 180°

25+x+40 180

65 +X= 180

X= 180 65

X 115
