Question

If plla, what is the value of x?
3y°
(2y + 25)°
(x + 15)°​

Answer 1

$\huge\bold{\underline{\underline{\star{\red{αиѕωєя}{\star}}}}}$

2y + 25 = 3y - alternate angles are equal.

25 = 3y - 2y

25 = y

Therefore,

2y + 25 = 2×25 + 25 = 50 + 25 = 75°

3y = 3 × 25 = 75°

Now,

75° = x + 25

75 - 25 = x

50 = x

Therefore,

x + 15 = 50 + 15 = 75°

Answer 2

Answer:

2y + 25 = 3y - alternate angles are equal.

25 = 3y - 2y

25 = y

Therefore,

2y + 25 = 2×25 + 25 = 50 + 25 = 75°

3y = 3 × 25 = 75°

Now,

75° = x + 25

75 - 25 = x

50 = x

Therefore,

x + 15 = 50 + 15 = 75°
