Answer»

Step-by-step EXPLANATION:

question 1

5x-60°+3x-80°+2x+40°= 180°( angle sum property of triangle )

10x+140°-40°=180°

10x=180°-100°

10x=80°

x=80°/10

x= 8 value of X is 8

question 2.=

∠=45°+∠ Y= 180° (angle on the same LINE)

y=180°-45°

y=135°

now,..............

∠ BOD+∠AOB=180° (angle on the same line )

135°+∠AOB=180°

AOB=180°-135°

∠ AOB=45°

in triangle ABO

∠A+∠B+∠O=180°

63°+x+45°=180°

108°+x=180°

x=180°-108°

x=72°
