Question

Find the value of x.

Answer 1

Explanation:

we know the inside total angles for triangle is 180 degrees.

We are given the two internal angles as 70 and 50 degrees.

So the equation can be written as

70+50+y = 180

y= 60

Also, we know that straight line is 180 degrees. Now we can write the second equation as follow:

60+x = 180

x = 120 degrees

Answer 2

`120^(\circ)`

Explanation:

Using the exterior angle theorem,
`x=50^(\circ)+70^(\circ)=120^(\circ)`.
