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

6. tan15=x/5

multiply 5 to both sides: x=5(tan15)

simplify: 4.01

How to find the hypotenuse of a triangle?
ExtremeBDS [4]
To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem

so a^{2} +  b^{2} =  c^{2}

a^{2}  is one of the legs

and 

b^{2}  is the other leg

then 

c^{2}  is the hypothenuse

Triangle ABC is an isosceles with a base AC. The base angles are 60 degrees. Find the length of the base and the length of the a
lisabon 2012 [21]

Answer:

base =5   because all angles=60, so an equilateral triangle

height=4.33

Step-by-step explanation:

height^2+1/2(5)^2=5^2

height^2+6.25=25

height^2=18.75

height=4.33

40.32 is 76.8% of what number?
julsineya [31]
Hey there

Lets solve this question together, 

Convert <span>76.8%</span><span> to a decimal.
</span>
0.768 * x=40.32 

Multiply 0.768<span> by </span>x<span> to get </span><span>0.768x</span><span>. 
</span>
&#10;0.768x=40.32 

Multiply<span> each </span>term<span> by </span><span>1 / 0.768</span><span> and simplify.
</span>
Cancel the common factor of 0.768.

x=40.32 / 0.768 

Divide 40.32<span> by </span>0.768<span> to get </span><span>52.5 

</span>x=52.5 <span>
