Please help me ASAP. Triangle Angle Theorems


The value of x is _____?

Answer 1

So exterior angles are equal to the opposite interior angles

So the equation would be:
25x+57+x=45x
26x+57=45x
57=19x
x=3

Answer 2

The value of x will be equal to 3.

What is the triangle?

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

We know that the  exterior angles are equal to the opposite interior angles

So the equation would be:

25x  +  57  +  x   =   45x

26x  +  57   =   45x

57  =   19x

x    =    3
