PLZ HELP!! WILL MARK BRANLYIST!!! 30 POINTS!!
V125BC [204]

Answer:

The distance between the light and the actor's face is 29.24 ft

Step-by-step explanation:

In the attached photo, you can see where the hypotenuse, the opposite side, and and adjacent side are located from the given angle measurement which is 70°. Our known side length is 10 ft which is our adjacent side and our variable is the hypotenuse. So, we will use <u>cos</u>.

Cos=\frac{adjacent}{hypotenuse}

Let's plug in our numbers and variable.

(Cos)70=\frac{10}{x}

Since our hypotenuse is a variable, we are going to flip the equation so we can find the value of the hypotenuse which is also our variable.

x=\frac{10}{(cos)70}

Divide 10 by (cos)70.

<em>x = 29.24</em>

So, the hypotenuse is 29.24 feet which shows the distance between the light and the actor's face.

Is 1.2/3 and 1.8/ 4/5 proportional
Stella [2.4K]

Answer:

No

Step-by-step explanation:

1.2/3 =0.4

4/5 can be written as 0.8

So, 1.8/0.8 = 2.25.

However, 1.8/4/5 is the same as:

1.8/1 ÷ 4/5

Keep Change Flip

1.8/1 x 5/4 = 9/4

(1.8 x 5=9 & 1 x4 =4)

9/4 =2.25

Solve the equation <br>8(4- x) = 7x + 2<br>x=​
Jet001 [13]

Answer: x=2

Step-by-step explanation:

Expand.

32−8x=7x+2

Add 8x to both sides.

32=7x+2+8x

Simplify  7x+2+8x7x+2+8x  to  15x+215x+2.

32=15x+2

Subtract 22 from both sides.

32−2=15x

Simplify  32−2  to  30.

30=15x

Divide both sides by 15.

30/15=x

Simplify 30/15 to 2

2=x

Switch sides.

x=2
