Answer: 180 = 30 + (x + 60)
Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
Answer:
2
Step-by-step explanation:
The distances have the ratio:
(C -A) = (2/3)(B -A)
C = (2/3)B +(1/3)A . . . . . add A
C = (2B +A)/3 . . . . . . . . combine terms
C = (2(4) +(-2))/3 = 6/3 = 2
The coordinate of C is 2.
Answer:
The discount is $4.50. The sale price is $25.50.
Step-by-step explanation:
Discount: 30(.15)=4.50
Sale Price: 30.00-4.50=25.50
Use all the top to multiply by it
Then divide by the buttom.
<em>A</em>=1/4 times the square root of
5(5+2 square root5) times apothem squared
Plug everything into the equation and you get
≈172.04774
The answer is about 172.05
