Question

the angles of a triangle are 2x, 3x and 5x. find x and the angles of triangle.

Answer 1

Answer:

x=18

Explanation:

The sum of the 3 angles in a triangle is 180∘

hence , the sum of the 3 angles given must equal 180

We can form an equation

2x + 3x + 5x = 180 ⇒10x=180⇒x=180/10
x=18


2(x) = 2(18)=36
3(18)=54
5(18)=90

Answer 2

as we know, sum of the angles of a triangle is 180°
so, in this case
2x+3x+5x=180°
10x=180°
x=180÷10=18
x=18
the angles are
2x= 2×18= 36°
3x=3×18=54°
5x=5×18=90°
ans: the angles are 36°,54° and 90° respectively. the value of x is 18°
