Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is ) and apply it to each side
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1
64
number 2)
Explanation step by step
Vertical angles are congruent (equal), and the angles below are vertical angles.
x + 40 = 3x
40 = 3x - x
2x = 40
<u><em>x = 20</em></u>
