27.	Plzz very urgent question 9
Answer» Let one angle be x Let the other angle be y x - y = 10 -------- (1) x + y = 90 -------(2) Solve (1) and (2) 2x = 100 x = 100/2 Therefore, x = 50 put x = 50 in (1) x - y = 10 50 - y = 10 - y = 10 - 50 - y = - 40 Therefore, y = 40 The two angles are 40 and 50 DEGREES.

27.

Plzz very urgent question 9

Answer»

Let one angle be x

Let the other angle be y

x - y = 10 -------- (1)

x + y = 90 -------(2)

Solve (1) and (2)

2x = 100

x = 100/2

Therefore, x = 50

put x = 50 in (1)

x - y = 10

50 - y = 10

- y = 10 - 50

- y = - 40

Therefore, y = 40

The two angles are 40 and 50 DEGREES.
