Question

plzzz do it que number 10

Answer 1

value of x is 50° ( coz angle DCA + angle RCA =180 complementary angles thefore angle ACB is 70° and x is 50°)

Answer 2

Given:-
angle B = 60°
angle DAC = 70°
AD || BC
Theorem:-
angle DAC & angle ACB are alternate angles
angle DAC = angle ACB... (alternate angles)
angle ACB = 70°
angle A + angle B + angle C = 180° ... (sum of all angles in a triangle is 180°)
x + 70°+ 60° = 180°
x + 130° = 180°
x = 180°-130°
x = 50°


Hope this sum helps you a lot.....
