ANSWER : it is a right angle
C = children
A = adults
293 = c + a
1.50c + 2.50a = 676.50
We can use substitution to solve:
c + a = 293 subtract a to get c = 293 - a
Plug this into the second equation:
1.50(293 - a) + 2.50a = 676.50
439.5 - 1.50a + 2.50a = 676.50
439.5 + 1a = 676.50
a = 237
Substitute this into the first equation:
293 = c + 237
56 = c
If LllM then consecutive interior angles should be supplementary
x-5+2x+5=180
x+2x=180
3x=180
x=60
Answer:x=60
A a^2 you wlc I think it’s right
