The product of 9 and the sum of three times a number and 8 is 180. what is the number? a) 4 b) 6 c) 12 d) 18

9(3x + 8) = 180

Distributive property.

27x + 72 = 180

Subtract 72 from both sides.

27x = 108

Divide both sides by 27.

x = 4

The value of x is equal to 4.

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
