Question

angle 1 = 2x-10° and angle 2 = 3x+20°, find x and hence angle 1 and angle 2.​

Answer 1

Answer:

10

Step-by-step explanation:

2x-10=3x-20

sending 2x to right side and -20to left side

20-10=3x-2x

10=1x

x=10

then angle 2x-10=20-10=10

then angle 3x+20=30+20=50

so the angles are 10,50

Answer 2

Answer:

x=34

Angle 1 = 2(34)-10=58

Angle 2 = 3(34)+20=122

Step-by-step explanation:

Linear pair

(2x-10)+(3x+20)= 180

5x+10=180

5x=180-10

5x=170

x=34
