Question

What is the value of x ?

Answer 1

Answer:50 degrees

Step-by-step explanation: The 105degrees angle forms a supplementary angle with the missing degrees in the triangle

so the missing value which is not requested is 180degrees-105 degrees=75 degrees

No we have two angles inside the triangle. We can now work out the missing angle for x

We know that a triangle adds up to 180 degrees

So x=180-55-75=50 degrees as the answer

Answer 2

B - 50

Explanation:

the exterior angle is 105, and as it's on a straight line, the interior angle is 180-105=75

75+55=130

angles in a triangle are 180

180-130=50
