Answer:
10° and 5
Step-by-step explanation:
For the first one, the triangle is equilateral. All the angles in a triangle add up to 180°, so you can determine that 6x=60°. Solve some more and you will get x=10°. For the second one, it is also an equilateral triangle. Since it's equilateral, you can say that all the sides are equal. So 6x-5=5x. Add 5 to both sides and get 6x=5x+5. So you know that x=5 because 5x+5 is the same as 6x.
