Question

the 3 sides of a quadrilateral are 76+54 and 108. find the measureof the fourth angle​

Answer 1

Answer:

We know that sum of quadrilateral is 360°.

Fourth angle=360-(76+54+108) =360-238 =122°.

Answer 2

$\huge\star\mathfrak\red\red{Answer}$

Sum of Quadrilateral = 360°

$\huge\star\mathfrak\red\red{Given}$

.➣

Three sides of quadrilteral = 76, 54, 108

.➣

Fourth angle = 360° - (sum of all the three sides)

= 360° -(76+54+108)

= 360° - 238°

= 122°
