Question

How do you do this?????????????

Answer 1

Hey there!

To find the value of an angle in a triangle, you need to add the 3 angles. You have angles with 55 degrees, 65 degrees, and x degrees. Put this into an equation. The equation would be 55+65+x=180. Simplify to get 120+x=180. You need to isolate x, so subtract 120 from both sides to get x=60. So the value of x is 60 degrees.

I hope this helps!

Answer 2

Hey there! :) To find the value of "x," we have to first find the other angles. Remember that every straight line adds up to 180°! :)

This is a fairly easy question, as you simply just ignore the inside triangles, as we are already given the angles.

Look at the bottom angles of the whole triangle - all you need to do is add 55° with 65°, then subtract the answer from 180°. Why? Simply because all triangles, added up, equal 180°.

So : 55° + 65° = 120°

180° - 120° = 60°

Therefore, x = 60°
