Answer 2

Answer:

Even though you mentioned that you didn't need a step-by-step explanation, I am still going to give one as some people who do not know how to solve it will be helped. 

Step-by-step explanation:

Before we start, you need to know two important concept about linear pairs and angle sum property.

Angle sum property- This is a property of a triangle. This is where all the angles of a triangle is added and the sum is 180°. Examples are given below.

Linear pairs-where the angles are side-by side and and the sum of these         2 angles are 180°. Examples are given below.

We first need to the other angles before we find x. Such as:

Let the value which is liner paired with 100° be = a

100° + a = 180°

a = 180°- 100°

a = 80°

Let the value which is liner paired with 125° be = y

125° + y = 180°

y = 55°

Now, we find x.

a + y + x = 180°

80°  + 55° + x = 180°

135° + x = 180°

x = 180° - 135°  

x = 45°

Hope it helps you!
