Again, this is a triangle so the sum of the angles must be 180°, so we can say:
a+b+c=180, we are told a=129, b=2c, we will let c=M°
129+2c+c=180 combine like terms on left side
129+3c=180 subtract 129 from both sides
3c=51 divide both sides by 3
c=17°
So angle M=17°
Answer:
A.1296
Step-by-step explanation:
Answer:
-6/7
Step-by-step explanation:
5 – 6x = 8x + 17
<=> 5 - 17 = 8x + 6x
<=> -12 = 14x
<=> x = -6/7
Answer: a = -5
Step-by-step explanation:
2(a+3)=-4
Distribute
2a+6=-4
subtract the six with the four and you get -10
-6-4=-10
now divide 2a with -10
you get a= -5
you can plug the answer in
$520
First, you multiply 26 by 4.
Then you multiply the product (104) by 5.
