Answer 2

Answer:

The greater angle is 4x+10

Step-by-step explanation:

we know that the some of interior angle of a triangle is 180 degree

$x + 4x + 10 + 4x - 10 = 180 \\ 9x = 180 \\ x = 20 \\ then \: \\ angle \: 1st \: is \: x = 20 \\ angle \: 2nd \: \: is \: 4x + 10 = 90 \\ angle \: 3rd \: is \: 4x - 10 = 70$
