Solving a right triangle ‼️ Can someone help me find B, b, and c❓Round to the nearest tenth.
Luda [366]

Answer:

see explanation

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° = \frac{opposite}{adjacent} = \frac{27}{b}

Multiply both sides by b

b × tan39° = 27 ( divide both sides by tan39° )

b = \frac{27}{tan39} ≈ 7.5 ( to the nearest tenth )

sin39° = \frac{opposite}{hypotenuse} = \frac{27}{c}

Multiply both sides by c

c × sin39° = 27 ( divide both sides by sin39° )

c = \frac{27}{sin39} ≈ 28.0 ( to the nearest tenth )

Solve the inequality.<br> - 5x &gt; 25
Natalija [7]

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.
