Question

Two angles of a quadrilateral measure 55° each. The third angle is 140°. What is the measure of the fourth angle?​

Answer 1

Answer:

110 ...Will be the answer

Answer 2

$\star \bigstar \mathbb{ANSWER} \bigstar \star$

Given ,

measure of the first angle = 55⁰

measure of the second angle = 55⁰

measure of the third angle = 140⁰

measure of the fourth angle = $x⁰$

$\therefore$ A/Q ,

$\implies$ 55⁰ + 55⁰ + 140⁰ + x⁰ = 360⁰

( angle sum property of a quadrilateral )

$\implies$ 110⁰ + 140⁰ + x⁰ = 360⁰

$\implies$ 250⁰ + x⁰ = 360⁰

$\implies$ x⁰ = 360⁰ - 250⁰

$\implies$ x⁰ = 110⁰
