Answer:

Height of the tree is approx 17.74 feet.

Step-by-step explanation:

the angle of elevation of the sun at 10:00 a.m. is 29°.

Then measure of angle C = 29°

At that point, a tree’s shadow is 32 feet long.

Then BC=32

Now we need to find about how tall is the tree.

So we can use trigonometric formula of right triangle to find missing height (x) of side AB.

\tan\left(C\right)=\frac{AB}{BC}

\tan\left(29^o\right)=\frac{x}{32}

\tan\left(29^o\right)=\frac{x}{32}

0.55431=\frac{x}{32}

0.55431*32=x

17.73792=x

Hence height of the tree is approx 17.74 feet.

6x + 4 - x = 2(x+1)


First combine like terms on the left side:

6x-x - 5x

So you have 5x+4 on the left side.


Then use the distributive property on the right side:

2(x+1) becomes 2x +2


Now you have 5x +4 = 2x +2

Subtract 4 from each side:

5x = 2x -2

Subtract 2x from each side:

3x = -2


Divide both sides by 3:

x = -2/3
