Answer =

hi

the value of x will be 34 as........

sum of supplementary angle is 180 degree

so, angle A + angle D = 180

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

after opening the bracket

5x + 10 = 180

x= 180-10÷5

x= 34

the value of y will be 115 as......

Sum of angle of trapezium is 360 degree

so , A + B + C + D = 360

(2 × 34 - 10) + 65 + (3 × 34 + 20) + Y = 360

(68 - 10) + 65 + (102 + 20) + Y = 360

58 + 65 + 122 + Y =360

245 + Y = 360

y = 360 - 245

y = 115

so ,X = 34 and Y = 150
