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

Answer:

The value of x is $26\°$

Step-by-step 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

$6x=180\°-24\°$

$6x=156\°$

$x=26\°$
