Answer:
x = 8
Step-by-step explanation:
Base angles of isoceles triangle are equal
5x + 10 = 50
5x = 40
x = 8
Answer:
The value of x= 7 and that of Angle A= 157°
Step-by-step explanation:
(x+16)° = (4x-5)° [Vertically opposite angles]
3x= 21
x= 7
Now, A + (4x-5)° = 180° [Linear pair]
A + [4(7)-5] = 180°
A + 23 = 180°
A = 180° - 23
A = 157°
