Answer:
![\frac{5\sqrt{34}}{34}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Csqrt%7B34%7D%7D%7B34%7D)
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r =
.
In the equation you'd write that as r =
which can be simplified to
.
You end up with
and you simplify this by doing
, ending with the result of
.
(I also got this answer right on the test.)
5 because 9 1/2 is 19/2 and 1 9/10 is 19/10 so to make a a common Denominator x5 and you’ll get 95/10 and 19/10 can go into 95/10 5x.
Answer:
The correct answers are A and E
Step-by-step explanation:
Answer:
Step-by-step explanation:
-5x - 3 = 2x - 18
-2 -2
-8x - 3 = -18
+ 3 +3
-8x = -15
/-8 /-8
x = 2.875
If you're doing the equal side
If you're not you would do
-5x -3 = 180
+ 3 +3
-5x = 183
/5 /5
x = 36.6
2x - 18 = 180
+18 +18
2x = 198
/2 /2
x = 99
Answer: 18- Hope this helps :)

Step-by-step explanation: The volume formula for a triangular prism is (height x base x length) / 2
All you must do is calculate it which is 4 x 3 x 3 = 36 and than you divide it by half and you get your answer- 18
