The measure of each angles
Aleks [24]
Supplementary angles is when 2 angles add up to 180 degrees.

We will name the smaller angle a and the bigger angle b.

therefore:

b - 172.6 = a

a + b = 180

Now we substitute:

a + b = 180
b - 172.6 + b = 180
2b - 172.6 = 180
2b = 352.6
b = 176.3

To find a:

a + b = 180
a + 176.3 = 180
a = 3.7

Therefore,

angle a = 3.7 degrees
angle b = 176.3 degrees.

Hope it helps and have a great day ahead

Solve for c. a(b-c)=d
Veronika [31]
A(b-c)=d
We are trying to leave c on one side, so we have to divide by a on both sides first to get
b-c=d/a
now we can subtract by b on both sides to get 
-c=d/a-b
now multiply both sides by -1 to get
<span>c=-d/a+b</span>

3.) If y vanes inversely as x, and y = 9 when x = 4, find y when x =12
natali 33 [55]

Answer:

y= 36

Step-by-step explanation:

if y varies directly as x, and y=9 when x=4, find y when x=16

.

When you see "direct variation" think:

y = kx

.

To find k, use "y=9 when x=4":

y = kx

9 = k(4)

9/4 = k

 

.

so, our equation is:

y = (9/4)x

.

now, we can answer:

find y when x=16

y = (9/4)x

y = (9/4)(16)

y = (9)(4)

y = 36
