Question

The angles of quadrilateral are 110, 72 and 55 and x degrees. find the value of x

Answer 1

I have written it step wise... if you dont need the steps you can directly write that the angles of a quadrilateral is equal to 360 so,
110 +72+55+x=360
237+x=360
x=360-237
x=123

Answer 2

Answer:

The value of x is 63°

Step-by-step explanation:

Given:

let A, B, C, D be the angles of a quadrilateral

∠A = 110, ∠B = 72, ∠C = 55 and ∠D = x

To find: ∠D i.e x

Solution:

we know that The sun of the angles of a quadrilateral is 360°

∵ ∠A + ∠B + ∠C + ∠D = 360°

=> 110 + 72 + 55 + x = 360

=> x = 360 - 237

∴ x = 63°

Hence, The value of x = 63°. Ans
