Question

Find the value of x please help

Answer 1

x=37

Explanation:

Area of triangle = x+x+x=180
= 78+65+x=180
=143+x=180
=x=180-143 (bring 143 to the otherside)
x=37

Answer 2

In the given figure, We are to find the respective value of x .

Solution :

We know that,

Sum of all the angles of the triangle = 180°

So,

`\qquad \sf \dashrightarrow{ x {}^( \circ) + 65 ^( \circ) +78 ^( \circ) = 180}`

`\qquad \sf \dashrightarrow{ x ^( \circ) + 143^( \circ) = 180^( \circ)}`

`\qquad \sf \dashrightarrow{ x ^( \circ) = 180^( \circ)} - 143^( \circ)`

`\qquad \bf \dashrightarrow{ x ^( \circ) = 37^( \circ)}`

Therefore, The value of x is 37°
