Answer:

134 degrees

the angles in a triangle always add up to 180.

86+48=134

to find the last angle you subtract 180-134

this gives you 46 degrees

-5n+4n-7=8
What is the answer for n and how do you solve it

Answers

Answer:

-15

Step-by-step explanation:

First combine like terms, aka the variables

-5n+4n-7=8

-1n-7=8

Then, isolate the variable by adding 7 to both sides

-1n-7+7=8+7

-1n=15

Finally, solve by dividing both sides by -1

-1n/-1=15/-1

n=-15

Answer:

n = -15

Step-by-step explanation:

I'll try my best to explain how I solved this

Equation:

-5n + 4n -7=8

Add the light terms on each side:

-n -7 =8

Separate the variables from the numbers:

-n = 15

Do the operation necessary to solve it:

n = -15
