Question

three angles of a quadrilateral meashre 70 85 and 90 .find the measure of the remaining angle of the quedrilateral​

Answer 1

Answer:

The total angle sum of quadrilateral is 360°

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360°

70° + 85° + 90° + x = 360°

245° + x = 360°

x = 115°

Answer 2

Answer:

GIVEN QUESTION:

THREE ANGLES OF QUADRILATERAL MEASURE 70°, 85°, 90°

FIND THE REMAINING ANGLES

SOLUTION:

IN A QUADRILATERAL SUM OF ALL ANGLES IS 360°

1ST ANGLE =70°

2ND ANGLE =85°

3RD ANGLE=90°

4TH ANGLE=X

70°+85°+90°+X=360°

245+X=360°

X=360°-245°

X=115°

THEREFORE THE 4TH ANGLE IS 115°
