If we know the measure of two of the three angles of a triangle, since the sum of the angles in a triangle aways is 180º, we can write the equation for angles a, b and c:

Let's suppose we know x and y, then z is:
Answer:
(0,3)
Step-by-step explanation:
just used what you gave me
Answer:
x = 13
Step-by-step explanation:
In a triangle, all the angles equal 180 so
2x + 5x - 7 + 6x + 18 = 180
combine like terms
13x + 11 = 180
13x = 169
x = 13
