A + 5 = -5a + 5 what does x equal

antoniya [11.8K]

Answer:

a = 0

Step-by-step explanation:

a + 5 = -5a + 5 subtract 5 from both sides

a + 5 - 5 = -5a + 5 - 5

a = -5a add 5a to both sides

a + 5a = -5a + 5a

6a = 0 divide both sides by 6

6a / 6 = 0 / 6

therefore,

a = 0

Urgent help needed with right triangle trig!

aliya0001 [1]

Let the unknown side's length be 'b' units .

Then by Pythagorean theorem . We have

${b}^{2} = {c}^{2} - {a}^{2}$
Now substituting the values of a and c in the above equation we get the value of b.

${b}^{2} = {24}^{2} - {6}^{2} = 540 \\ \\ b = \sqrt{540} = 6 \sqrt{15}$
We know that ;

$\tan( \theta) = \frac{b}{a} = \frac{6 \sqrt{15} }{6} = \sqrt{15}$
