Hello

First you have to remove your parenthesis and since there is a “+” in front of the parenthesis, the expressions remain the same. So:
9.88+6.7-x = 2,6

Now, you have to add the numbers. So:
16.58-x = 2,6

Next, you have to move the constant (x) to the right and change its sign since it changes side. So:
-x = 2,6-16,58

Now, calculate the difference:
-x = 13,98

And lastly, change the signs on both sides of the equation since - + - equals +. So:
x = 13,98

I don’t understand how to find the height
ANTONII [103]

Answer:

<u>height</u><u>,</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>2</u><u>3</u><u>5</u><u> </u><u>ft</u>

Step-by-step explanation:

From trigonometric ratios:

\cos( \theta)  =  \frac{adjacent}{hypotenuse}

but:

\theta = 90 \degree - 36 \degree \\  \theta = 54 \degree

adjacent is x

hypotenuse is 400 ft

\ \cos ( 54 \degree)  =  \frac{x}{400}  \\  \\ x = 400 \ \cos (54 \degree)  \\ x = 235 \: \:  feet
