Answer:
C = 18.1°
Step-by-step explanation:
A = 142 m²
a = 24 cm, b = 38 cm
Use the formula A = a*b*sinC/2
142 = 24 * 38 * sinC/2 = 456*sinC
sinC = 0.3114
C = 18.1°
Answer:
$6.96
Step-by-step explanation:
(4*8.99) + (3*7)
35.96 + 21 = 56.96
50- 56.96 = -6.96 So she owes 6.96

Step-by-step explanation:
This is a hyperbola.
Answer:
88 degrees
Step-by-step explanation:
This is an isosceles triangle, meaning that the interior angles next to the base will always be the same.
The interior angles of a triangle will always add up to 180 degrees.
So:
46 + 46 = 92
180 - 92 = 88 degrees
