Question

A quadrilateral has three acute angles each measuring 85º. Find the measure of the fourth angle.​

Answer 1

Answer:

7.i. sum of all angles of quadrilateral=360

three angles are given85,85,85

let fourth angle = X

now , sum of all angles of quadrilteral =360

85+85+85+X=360

255+X=360

X=360-255

X=105

fourth angle = 105

Step-by-step explanation:

Answer 2

The fourth angle is 120 ° .
