Lets solve the first part first.
8(6a+7b)
Distribute the 8 to the 6a and 7b
48a+56b
Now the next half
-11(2b+8a)
Distribute the -11 to 2b and 8a
-22b-88a
Then we have to combine 48a 56b -22 b -88a
48a-88a= -40a
56b-22b= 34b
-40a+34b

What is the measurement of each angle

user100 [1]

Answer:

$7(14)-11=87\\\\5(14)-2=68\\\\2(14)-3=25$

Step-by-step explanation:

First we need to set up an equation in order to find the value of x. We know that the sum of these angles are 180°

$7x-11+5x-2+2x-3=180\\\\14x-16=180\\\\14x=196\\\\x=14$

Now we can plug in our value for x into each of the angle's equations

$7(14)-11=87\\\\5(14)-2=68\\\\2(14)-3=25$

Solve for a. ab +c=d a=b/(c-d) a = (d - C)/b a=b+c/d
