Answer:
a=35 given
b=40
c=110
I couldn't complete see c. Please look at the picture to see what I assumed it to be.
Step-by-step explanation:
Hmmm... I guess a and b are not vertical.
We are given b=180-4a and a=35 so b=180-4(35)=180-140=40.
So b=40.
Isosceles triangles always have congruent base angles. So let's call both of the base angles in the bottom triangle x.
That means x+x+40=180.
We need to solve this for x.
Combine like terms:
2x+40=180
Subtract 40 on both sides:
2x=140
Divide both sides by 2:
x=140/2
Simplify:
x=70
So I'm assuming that c and it's adjacent angle are sitting on a straightedge together which means 70+c=180.
70+c=180
Subtract 70 on both sides:
c=180-70
Simplify:
c=110
Step-by-step explanation:
s:t=2:3
t:u=2:3
s:u=?
s/u=2/3
Answer:
Halp u
Step-by-step explanation:
Answer: 1200 inches long.
Step-by-step explanation:
the enlargement went from 1 inches wide to 80 inches wide.So which means it was being multiply by 80.
so you have to multiply 15 by 80 to find length of the enlargement or how long the enlargement of the design will be.
15 * 80=1200
Answer:
0.0130 m per min. to 4 decimal places.
Step-by-step explanation:
If 2 m^3 of water is added we have volume = 2 = π 7^2 h where h is the height:
h = 2 / (π 7^2) = 0.01299 m.
