Question

 In a quadrilateral ABCD, ∠A = 100 degree, ∠B = 65degree and ∠D =125 degree. Find the measure of ∠C​

Answer 1

Answer:

angle C=70

Step-by-step explanation:

100+65+125=290 since a quadrilateral is 360 substract 290 to 360 and the answer is 70

Answer 2

Answer:

m∠C = 70°

Step-by-step explanation:

m∠A + m∠B + m∠C + m∠D = 360°

m∠C = 360° - (100° + 65° + 125°) = 70°
