First let's find y. We know the sum of angles equals 180, so if we add the angles of ABC, we'd get 180.
30+y+80+y=180
110+2y=180
2y=70
y=35
You could solve x ,but the only response with y=35 is c. But to solve for x, you'd ad 35 35 and xwhich would equal 180.
35+35+x=180
70+x=180
x=110
Answer:

Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have



The cost for the legs is

The cost for the hypotenuse is

So the total cost in term of h is

First, he paid 5/6 of the sticker price. He paid $29725 before the tax.
Then he paid a 7.25% sales tax. This can be found by multiplying $29725 by 1.0725
The final answer is C: $31,880.06
Answer:
x = 111
Step-by-step explanation:
126+158+120+125+121+139 = 789
900-789 = 111
(n-2)*180
5*180 = 900
Answer:
y=1
