Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° = 
= 
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b = 
≈ 7.5 ( to the nearest tenth )
sin39° = 
= 
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c = 
≈ 28.0 ( to the nearest tenth )
Perimeter=(side a • 2) + (side b •2)

Answer and Step-by-step explanation:
Divide -5 from both sides of the inequality.
<u>x < -5 is the answer.</u>
<u></u>
<em>Here's Why:</em>
If you were to add 5x to both sides, it results in this:
0 > 25 + 5x
Now, we subtract 25 from both sides.
-25 > 5x
When we divide 5 from both sides, we see that it results in -5 > x, which is the same as x < -5.
