Answer: 42.8°F
Step-by-step explanation: 6°C is 42.8°F
Answer:
First you'll find the equation of the graphed line in slope-intercept form, y = mx+b, and then from there we'll convert it into standard form, ax+by = c. To find the slope of the line you could either use the two points on the line or just look and see.

Answer:
x = 40°
Angle A: 118°
Angle B: 120°
Angle C: 62°
Angle D: 60°
Step-by-step explanation:
When a quadrilateral is inscribed inside a circle, opposite angles add up to 180.
(x + 20) + 3x = 180
4x + 20 = 180
4x = 160
x = 40°
Angle A: 2(40) + 38 = 118°
Angle B: 3(40) = 120°
Angle C: 180 - 118 = 62°
Angle D: 40 + 20 = 60°
