Find X
What Is The Equation To AB=
Rounded To The Nearest Hundredth.

x = 7.449

Step-by-step explanation:

CAH

cos 20 = 7 / x

x = 7 / cos 20

x = 7.449

This one is little complicated than the other one, first you have to find the missing angle. we do that by:

90 + 20 + x = 180

110 + x = 180

x = 70

now we use the sin formula:

sin 70 = 7 / x

x = 7 / sin 70

x = 7.449

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
