Answer:
x=19
Step-by-step explanation:
We know that the interior angles of a triangle add up to 180 degrees. We already have one angle, the bottom one, so let's just get that out of the picture by subtracting it from 180. The other two angles add up to be 80 degrees. What we can do is combine them together and get 4x-4=80. We have 4x because of x+3x. It equals 80 because that's what the two angles together add up to be. What we want to do now is get x by itself. Subtract 4 from both sides and get 4x=76. Now, we divide by 4, to undo multiplication. We are left with x=19, and now we have our answer.
Answer:
D. 220.16 Square feet
Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is 
. So we fill in this equation with the information we already know:
Simplify the exponents
Multiply
So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple 
which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.
1024-803.94= 220.16 square feet
The percentage discount is 80%
80% of 50 is 40.
I hope this helps.
Answer:
The answer to your question is the letter B. 3,037
Step-by-step explanation:
Data
b = 600
B = 11°
C = 75°
c = ?
Process
1.- To solve this problem, use the law of sines
b/sin B = c/sin C
2.- Solve for c
c = b sin C / sin B
3.- Substitution
c = 600 sin 75 / sin 11
4.- Simplification
c = 600 (0.966) / 0.191
c = 579.55 / 0.191
5.- Result
c = 3037
