Because a triangle's angles need to equal 180, you can subtract 100(30+70) and you will get 80. So 80 will be your third angle.
Answer:
c
Step-by-step explanation:
Subtract 100 from both sides to get x by itself.
x = 163
(Another way of writing this is "263 - 100 = " like you would see in elementary school.)
(p - 0.15p) + 1.99
This is the equation to solve.
p minus 15% of p, plus 1.99 for shipping costs.
It’s either a or b i’m not sure
