Question

if three angles of a parallelogram are 85 degree, 117 degree and 45 degree, find the other angle in degree.

Answer 1

Answer:

113

Step-by-step explanation:

85+117+45+x=360

x=113

Answer 2

Answer:

113 degrees

Step-by-step explanation:

Sum of all 4 angles in a quadrilateral= 360 degrees

Measure of first angle= 85 degrees

Measure of second angle= 117 degrees

Measure of third angle= 45 degrees

Measure of fourth angle= 360- (sum of the other angles)

= 360- (85+117+45)

= 360- 247 degrees

= 113 degrees
