1 answer:

7 0

Answer:

In order to find out the tangent value of 45 degrees, we need to divide the opposite side to the angle by the adjacent side. Since both the opposite and adjacent sides of this triangle are the same, we can see that tan(45) is equal to 1.

35=3x+14 could anyone help me fast please I also need to show work!

Neporo4naja [7]

Answer:

$\boxed {\tt x=7}$

Step-by-step explanation:

We are given the equation

$35=3x+14$

We want to solve for x, therefore we must isolate x on one side of the equation.

14 is being added to 3x. The inverse of addition is subtraction. Subtract 14 from both sides of the equation.

$35-14=3x+14-14$

$35-14=3x$

$21=3x$

x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.

$\frac{21}{3} =\frac {3x}{3}$

$\frac{21}{3}=x$

$7=x$

Let's check our solution. Plug 7 in for x and solve.

$35=3x+14$

$35=3(7)+14$

$35=21+14$

$35=35$

This checks out, so we know our solution, <u>x=7 </u>is correct.
