15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
Answer:
y=2x+15
Step-by-step explanation:
h=9
The slope is the coefficient of x when the coefficient of y is 1.
The slope is -0.5
The y-intercept is where x=0
y = 17 - 0.5 (0)
y = 17
The y-intercept is 17.
5.1/sin 60 = b/sin 80
cross multiply
b Sin 60 = 5.1 Sin 80
Divide both sides by Sin 60
b = 5.80
85 is the measure of a missing angle
