Answer:
x = 23
Obtuse scalane triangle
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
110+35+x+12 = 180
157 + x = 180 subtract x from both sides
x = 23
The given triangle is an obtuse scalane because it has no eqaual side lengths or angles measurment.
Using the lowest common multiple helps because then afterwards there is no need to divide because it’s already the lowest (I believe I was taught this a while ago).
96 adult
24 child
You can get this by setting adult tickets = x and child tickets = y. Then you have the total tickets equation as:
x - 4y = 0
and the cost equation as:
9.2x + 5.2y = 1008
