Question

The interior angles of a triangle have measures (2x−5)° , (4x−1)° , and 30°. What is the value of x?

Answer 1

180= 2x-5 +4x-1 +30
156= 6x
x= 26

Answer 2

The value of x is
`26\°`

Explanation:

we know that

The sum of the internal angles of a triangle must be equal to
`180\°`

so

`(2x-5)\°+(4x-1)\°+30\°=180\°`

solve for x

`6x=180\°-24\°`

`6x=156\°`

`x=26\°`
