Answer:
-0.2 x
Step-by-step explanation:
=> 0.8x-x
<u>Taking x common</u>
=> x (0.8 - 1)
=> x (-0.2)
=> -0.2 x
Using the catchphrase SohCahToa, we can determine that the cosine ratio is equal to the length of the side adjacent to the angle over the length of the hypotenuse of the right triangle.
To find the cos∠A, we will look for side lengths BC and AB.
cosA =
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
Since
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
is already in it's simplest form, we can conclude that the cosine of ∠A is
![\frac {9}{41}](https://tex.z-dn.net/?f=%5Cfrac%20%7B9%7D%7B41%7D)
.
Hope this helps! :^)
Answer:
- 127.3
- 52.7
- 127.3
- 52.7
Step-by-step explanation:
Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).
52.7 + x = 180
x = 127.3
Best of Luck!
