Question

The measure of two angles of a quadrilateral are 115º and 45° and the other two angles a
equal. Find the measure of each of the equal angle
s.​

Answer 1

Answer:

100

Step-by-step explanation:

Let the other two equal angles be x

then,

115+45+x+x=360 (sum of all angles of

quadrilateral is 360)

160+2x=360

2x=200

x=100

Therefore,the other two equal angle measures 100 each

Answer 2

Answer:

115°, 45°, 100°, 100°

Step-by-step explanation:

∠A+∠B+∠C+∠D = 360°

115°+45°+X+X = 360° (X are equal)

115°+45°+2X = 360°

160°+2X = 360°

2X = 360°-160°

2X = 200°

X = 200°/2

X=100°
