Answer:
The length of AB is 4.33012701892
Step-by-step explanation:
1. You find 10*sin(60 degrees), because sin(60 degrees) = x/CT, and CT = 10. That means that sin(60 degrees) = x/10. You multiply by 10 on both sides, which would mean that x = 10sin(60 degrees) and that AT = 8.66025403784 because x is AT.
2. Then, because the relation between AT and AB and Angle T is sine, you use cosine to find x. If you do that, you find that the equation is sin(30 degrees) = x/8.66025403784. That means that 8.66025403784*sin(30 degrees) = x. If you calculate that, you find that x = 4.33012701892, and AB is x.
Sarah scored 82 points on her first test of the year. On the second test,
82%
On the Second Test, She scored 77 points
77%
82
-77
=5
The Percent of Change is 5%
or -5% Because The second test Is lower than her first test
I’m guessing they are the same shaped, just enlarged. So all you gotta do if so is 18/10 which gives you 1.8 and then 7 x 1.8, this will give you 12.6
So the answer is 12.6, sorry if I’m wrong
Answer:
$9.25
Step-by-step explanation:
2.75+ .5(13)
.50 (13)= 6.5
6.5 +2.75= 9.25
Answer:
158
Step-by-step explanation:
2(x square + y square)
2 (X+y) square -2 xy
2(10) square -2(21)
2×100-42
200-42
=158
