Answer: $ 38.69 ; There are 12 people in the crew
Answer:
90 and 10
Step-by-step explanation:
Because it is an isosceles triangle, the two base angles have to be the same, so
36°+36°=72°
angles in all triangles add up to 180°, so
180°-72°=108°
unknown=108°
X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
The coefficient in (2/3q-3/4) is 2/3 and in (-1/6q-r) is -1/6
