Question

One angle of a triangle is 65°. Find the remaining two angles if their difference is 20°.​

Answer 1

Step-by-step explanation:

By angle sum property-

m<1 + m<2 + m<3= 180° (<= angle)

65° + x+ y= 180

x+y=180°-60°

x+y = 120°

y= 80° x=60°

= 80°-60°

20°

Answer 2

Answer:

67.5

Step-by-step explanation:

Let one angle be x

other angle be ( x- 20)

= 65 + x + ( x - 20 ) = 180

= 65 + x + x - 20 = 180

= 45 + 2x = 180

= 2x = 180 - 45

= 2x = 135

= x = 135/2 = 67.5
