Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle , then
15x + 5 + 22x + 4 = 120
37x + 9 = 120 ( subtract 9 from both sides )
37x = 111 ( divide both sides by 37 )
x = 3
Answer:
pq = 7
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = p(5, 4) and (x₂, y₂ ) = q(- 2, 4)
pq = 
= 
= 
= 7
Answer:
y= −9.16x²+73.04x+183.3
Values increase till x = 4 and then decrease which means thus curve has a maximum turning point around 4.
Coefficient of x² should be negative
because max to (concave down)
x = -b/2a should be around 4
x = -73.04/(2×-9.16) = 3.987
