Find x. Then find the measure of angles A, B and C.
mafiozo [28]

Answer:

x= 11

A=59

B= 37

C = 84

Step-by-step explanation:

A triangle adds up to 180 °.

So the equation will be a °+ b° + c° = 180°

Next, you combine like terms.

6x + 3x + 9x+4-15-7 = 180\\18x-18=180

Then inverse operation,

18x-18=180\\18x=198\\x=11

After to get a, b, and c you just need to plug in x.

6(11)-7=a\\3(11)+4 = b\\9(11)-15=c

Question
Aleonysh [2.5K]

Answer:

\large \boxed{-40, \ 4, \ -4}

Step-by-step explanation:

f(x)=-9x+14

\sf Put \ x \ as \ 6.

f(6)=-9(6)+14

f(6)=-54+14

f(6)=-40

g(x)=-3x^2

\sf Put \ g(x) \ as \ -48.

-48=-3x^2

\displaystyle \frac{-48}{-3} =\frac{-3x^2 }{-3}

16=x^2

\sqrt{16} =\sqrt{x^2 }

x= \pm 4

inna [77]

Answer:

B.

Step-by-step explanation:

Use elimination, or you can plug the answer choices into the eguations. Plugging in the answer choices does take a while though. If you don't know how to do elimination then basically you try to make one of the three values equal to the other in the opposite equation. MAKE SURE TO DO THE FACTOR FOR ALL OF THE VALUES IN THE EQUATION. once you solved it, you then plug in the value back into one of the equations and you find the other value.
