Question

the three angles of a quadrilateral are 50degree 85degree 116degree. find the fourth angles.​

Answer 1

Answer:

109

Step-by-step explanation:

we know that the sum of all interior angle of quadilateral is 360degree

85+116+50+x=360x=109

Answer 2

Answer:

Fourth angle=109°

Step-by-step explanation:

∠A=50°, ∠B=85°, ∠C=116°

∠A+∠B+∠C+∠D=360°

50°+85°+116°+∠D=360°

251°+∠D=360°

∠D=360°-251°

∠D=109°

Therefore, the fourth angle is 109°.
