In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒ x = 40/2 = 20°
4x + 13y = 40
4x + 3y = -40
multiply second equation by -1
4x + 13y = 40
-4x - 3y = 40
add equations together
10y = 80
y = 8
put y in either original equation
4x + 3(8) = -40
4x + 24 = -40
subtract 24 from both sides
4x = 64
x=16
y=8
Answer:
2x + 15 = -23
x = -19
Step-by-step explanation:
2x + 15 = -23
2x+ 15-15 = -23 -15
2x = -38
2/2x = -38/2
x = -19
