Question

3. A quadrilateral has three acute angles each measuring 70degree
What is the measure of the fourth angle
​

Answer 1

Answer:

Step-by-step explanation:

we know that sum of angles of a quadrilateral is 360

let the angles be A,B,C,D

A=70

B=70

C=70

D=?

A+B+C+D     =360

70+70+70+D=360

210+D           =360

D                   =360-210

D                   =150

THEREFORE THE MEASURE OF THE FOURTH ANGLE IS 150
