Interior angles in any triangle sum up to 180 so 180-(30+40)=110
So the exterior angles equals 180-110= 70
70 is the final answer i hope it helps and good luck
Answer:
22?

Answer:
Step-by-step explanation:
The Law of Sines is given by and works for every triangle.
Substituting given values, we have the following equation:
*Note that because , when solving for an angle with the Law of Sines, there may be two answers. However, since the problem designates angle C as an acute angle, the other angle is negligible.
The triangle to the top right is missing one angle. We know the sum of all angles in a triangle add up to 180 degrees. We already have 35 + 90 = 125 degrees, so the last angle must be 55 degrees. That angle is verticle to another angle, which you should be able to notice (also 55 degrees because vertical angles are congruent). Now, we have 67 + 55 = 122 degrees in that triangle. It must add up to 180, so the unknown angle is 58 degrees.
