Answer:

x = 12

Step-by-step explanation:

Since we are given a right angle, we can say that:

sum of all angles = 90 degrees

x + 42 + 3x = 90

4x = 48

x = 12

So, x is equal to 12 degrees!

Hope this helps))) ^‿^

How do I solve this to find angle G?

Answer:

Step-by-step explanation:

The angle at E is 90 degrees.

All tangents of a circle always meet the radius at a 90 degree angle.

90 + 67 + G = 180o All triangles have 180 degrees. Combine left.

157 + G = 180o Subtract 157 from both sides.

157 - 157 + G + 180 - 157

G = 23
