You can find the missing angle measure by using the triangle sum or something like that formula lol

Step-by-step explanation:

102+48= 150

180-150= 30

So 30 is the measure of the missing angle :)

To begin, remember that the sum of all angles must equal 180.

With that being said, take your two known angles into account.

1 - X = Unknown

2 - 102

3 - 48

To find x, simply add 102 and 48.

102 + 48 = 150, the sum of angle 2 & 3.

Remember that the sum of the whole figure must be 180. With that being said, subtract 180 and 150.

180 - 150 = 30

x = 30

To double check, add all the sides together.

102+48+30 = 180

5+2x=a
