Answer:

76 degrees

Step-by-step explanation:

We know that supplementary angles equal 180 degrees. So, set up the equations:

180=(x+15)+(x-13)\\

180=(2x+2)\\

178=2x

x=89\\

Then, you just plug 89 back into ZB, and simplify:

(89-13)\\

=76

So, the measurement of angle ZB is 76 degrees.

1. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

2. c= 90-40= 50 (vertically opposite angles)

b=a=360-90-90=180/2=90 (angles at a point)

3. a= 180-52-51= 77 (angles on a straight line)

b=52 (angles at a point)

d=51 (angles at a point)

c=77 (angles at a point)

4. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

e=65

d=f= 360-65-65=230/2=115

h=55

i=g=360-55-55=250/2=125

5. b=163

a=90

e=70

d=360-70-70=220/2=110

c=360-163-163=34/2=17

Hope this helps!

Use the functions f(x) and g(x). to evaluate below.
svet-max [94.6K]

Given the graph and the table of functions, f(x) and g(x), the following <em>evaluated</em>:

a. f(0) = 9

b. g(2) = -3

c. f(-1) = 5

Given the functions, f(x) and g(x), the following can be <em>evaluated</em>:

<em><u>a. Find f(0):</u></em>

Using the table given, what we need to determine is the of the output, f(0) that an input value, x = 0, will give.

  • From the table, we see that when x = 0, f(x) =9.

<em>Therefore,</em>

f(0) = 9

<em><u>b. Find g(2):</u></em>

From the graph, find the corresponding value of g(x) that corresponds with x = 2.

  • From the graph, when x = 0, g(x) = -3

<em>Therefore,</em>

g(2) = -3

<em><u>c. Find f(-1):</u></em>

From the table, find the corresponding value of f(x) that corresponds with x = -1.

  • From the table, when x = -1, f(x) = 5

<u />

<em>Therefore,</em>

f(-1) = 5
