1. sqrt 52 = 7.211 rounds to 7

2. irrational number

3. sqrt 441 = 21....rational

4. 12^2 + 3^2 = h^2
    144 + 9 = h^2
     153 = h^2
      sqrt 153 = h
      12.4 = h <===

5. 6^2 + b^2 = 18^2
    36 + b^2 = 324
    b^2 = 324 - 36
    b^2 = 288
    b = sqrt 288
    b = 16.97 rounds to 17 <==

6. 39^2 + 52^2 = c^2
    1521 + 2704 = c^2
    4225 = c^2
    sqrt 4225 = c
    65 = c
    (39 + 52) - 65 = 91 - 65 = 26 miles shorter <==

7. 4^2 + b^2 = 16^2
     16 + b^2 = 256
     b^2 = 256 - 16
     b^2 = 240
     b = sqrt 240
     b = 15.49 rounds to 15.5 <==

URGENT kaser needs $155 to pay for a new mouth piece for her saxophone she has $35 already and save $15 a week that she earns wa
yulyashka [42]

Answer:

A) she needs to earn $120 for her mouth piece

B) it will taker kaser 8 weeks to get enough money for the mouthpiece

Step-by-step explanation:

whats a segment tool? no idea but i can help solve this so you can attempt that part

explaining

so kaser needs $155, she already has $35 and gains $15 a week. i will be assisting you with how to solve for how much she has when she starts saving and how long until she saves it all

process A

155-35 = 120

answer A

she needs to earn $120 for her mouth piece

process B

120 divided by 15 = 8

answer B

it will taker kaser 8 weeks to get enough money for the mouthpiece

Select the correct answer from each drop-down menu. Right triangle ABC is represented with the right angle at vertex B. Base BC
Svetradugi [14.3K]

By using trigonometric relations, we will see that:

AC = 15.6 in

AB = 8.4 in.

<h3>How to get the measures of the other two sides of the right triangle?</h3>

Here we have the right triangle where:

B = 90°

C = 40°

BC = 10 in.

Notice that is the adjacent cathetus to the angle C, then we can use the two relations:

  • sin(a) = (adjacent cathetus)/(hypotenuse).
  • tan(a) = (opposite cathetus)/(adjacent cathetus).

Where:

  • hypotenuse = AC
  • opposite cathetus = AB.

Then we will have:

sin(40°) = 10in/AC.

AC = 10in/sin(40°) = 15.6 in

tan(40°) = AB/10in

tan(40°)*10in = AB = 8.4 in.

So we can conclude that for the given right triangle we have:

AC = 15.6 in

AB = 8.4 in.
