Alicia is x years old. her aunt is three times her age. in 8 years, their total combined age will 48 years.

a. write a linear equation for their total age in 8 years.

b. find alicia and her aunt's present age.

first answer will get brainiest.

Step-by-step explanation:

Parking lot:

Alicia=x

Aunt=3x

48=(Alicia+8)+(aunt+8)

48=x+8+3x+8

48=4x+16

Part a: 48=4x+16

Part b:

48=4x+16

32=4x

8=x

Angie is currently 8 years old.

Aunt=3x=3•8=24

Alicia's aunt is currently 24 years old.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
