damaskus [11]3 years ago
5 0

Answer:

1.  42.0 meters

2. 16.8

3.  2.3

4.  24.7

5. a. 42.4  b. 10.7

6.4.01

Step-by-step explanation:

1.    so by using soh cah toa: tan40 = x/50

multiply both sides by 50 :  (tan40)50=x

simplify: 42.0m

2. same concept but different values:  tan35=x/24

multiply 24 to both sides: (tan35)24=x

simplify : 16.8m

3. tano^-1 = 20/100

multiply both sides by tan^-1: the angle = tan^-1 (20/100)

Simplify: 2.3 degrees

4. cos o^-1 = 4.6/10

multiply both sides by cos^-1: the angle= cos^-1 (4.6/10)

simplify: 24.7

5. a. tan23= x/100

multiply 100 to both sides: x= 100(tan23)

simplify :42.4

b. you have to find the total height of the building with the antenna and then subtract the height of the building that you found in part a.

tan28=x/100

multiply 100 to both sides : (tan28)100=x

simplify 53.1

subtract the answer to part from 53.1:

53.1-42.4=10.7

-9=-3(x+2)<br>solve for x <br>show steps
lianna [129]

SimplifyOkie dokie so first things first, you have to get rid of those parentheses! To do this you use the distributive property. -3(x+2) is the same thing as -3(x)+-3(2). that and you get -9=-3x-6. So you want to get x by itself to be able to find what x is, so you add 6 to both sides of the equation to get rid of the -6. So then you get -3=-3x. Then you must divide both sides by the coefficient of x, which would be -3. When you divide both sides by -3 you get -3/-3=x, which is the same thing as 1=x. Hope this helped!

Answer:

<h2>1.5</h2>

Step-by-step explanation:

-----------------------------

Here's how we solve the equation

-1.2\left(3-x\right) = -1.8

-1.2\left(3-1.5\right) = -1.8

-3.6+1.2\cdot1.5 = -1.8

1.2\cdot1.5 = -1.8

-----------------------------

A basketball player scores 28 points in
Dmitriy789 [7]

Answer:

d) 80

Step-by-step explanation:

(35% = 0.35)

equation:

⇒ 0.35x = 28

divide 0.35 on both sides

⇒ \frac{0.35x}{0.35} = \frac{28}{0.35}

solve:

⇒ x = 80

Find the missing factor 5y^2-4y-9=(y+1)
disa [49]

Answer:

y = {1,2}

Step-by-step explanation:

5y^2 - 4y - 9 = y + 1

5y^2 - 5y - 10 = 0

5(y^2 - y - 2) = 0

5 (y - 2) (y - 1) = 0

y = {1,2}
