Answer:
x = 6
Step-by-step explanation:
Use the exterior angle theorem, which states that the 2 opposite interior angles add up to the measure of the exterior angle.
Set up an equation:
(8x - 13) + (9x - 10) = 11x + 13
Add like terms and solve for x:
17x - 23 = 11x + 13
6x - 23 = 13
6x = 36
x = 6
So, x = 6
Answer:
39
Step-by-step explanation:
Let's first take the ones with numerical values into play. If you add the second and the third equations, you get 10 = 2(shoe), so the shoe is 5. Then the helmet is 4. Taking the first equation, shirt-5=4+4, so shirt = 8+5=13. Then, we have Goal post = 4+13=17. The question mark is 13+9+17=39.
