In the diagram, what is the measure of angle 1? (image below) a. 15° b. 45° c. 135° d. 125°

3x + 9x = 180

12x = 180

x = 15

Angle 1 = 3x

3(15) = 45

B. 45°

T he answer is B 45 degrees

explanation

set up an equation

3x + 9x = 180

solve for x

x = 180/12 = 15

so, the angle 9x is 135 degrees

angle 1 is supplementary so, :

<1 = 180 - 135 = 45

d

step-by-step explanation:

the solution is in the picture

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
