We'll just give the sides a variable, the <span>hypotenuse is A, the height is B and the bottom length is C
A = 21
C = 15
This means the B = is </span>14.696938456699069 which is rounded to 15. But, this doesn't matter.
As long as we know the hypotenuse and one side we can find out that x is equal to about 45.584691402807024, round this to 46.
46 degrees is the answer.

What is 2 = 8 − 6/4x solved?

KengaRu [80]

Answer:

$x=4$

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

<u /> $2=8-\frac{6}{4} x$ <u />

<u />

<u>Step 2: Solve for </u><em><u>x</u></em>

Subtract 8 on both sides: $-6=-\frac{6}{4} x$
Divide both sides by -6/4: $4=x$
Rewrite: $x=4$

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

Substitute: $2=8-\frac{6}{4}(4)$
Multiply: $2=8-6$
Subtract: $2=2$
