Question

Find the value of x then classify the triangle by its angles

Answer 1

x = 134°

Explanation:

Let

`\angle A=64^(\circ)\\\\\angle B =70^(\circ)`

We need to find the value of x.

We can see from the figure that x is exterior angle. To find x we can use exterior angle theorem. According to this theorem,

`x=\angle A+\angle B\\\\x=64+70\\\\x=134^(\circ)`

Hence, the value of x is 134°
