Question

Anybody pls answer this genuinely ....

in a rhombus ABCD , ∠C and ∠D are *adjacent angles* . (Find x)
∠C = (7x - 3)°
∠D = (4x+5)°

note that the sum of any two adjacent angles of a rhombus = 180°

Answer 1

Answer:

Given:

∠C = (7x - 3)°

∠D = (4x+5)°

ATQ:

∠C + ∠ D = 180° (sum of two adjacent angles is 180°)

Therefore

(7x - 3) + (4x+5) = 180

7x - 3 + 4x + 5 = 180

11x +2 = 180

11x = 180-2

11x = 178

x = 178/11

x = 16.1 °
