  1. About 127.3(square root of 16,200, or 90√2)  Look at this problem like a right triangle.  Each leg is 90 feet, so the hypotenuse is the square root of 90^2 + 90^2
  2. About 52.3(square root of 2735.64)  Another right triangle problem!  Once again, with Pythagorean theorem (a^2 + b^2 = c^2) You can deduce that 60^2 = 29.4^2 + the width of the TV^2.
  3. About 11.6(Square root of 134.75)Another right triangle problem, you can deduce that 9.5^2 + The pool length^2 = 15^2

Hope it helps <3

(If it does, please give brainliest, only need one more for rank up :) )

Answer:

2. 18\sqrt{5}

3. 52.303...

4. 11.608...

Step-by-step explanation:

2. Using the Pythagorean Theorem, we can see that a^2+b^2=c^2. Therefore, 90^2+90^2=8100+8100=c^2. We know that 8100+8100 is 16200. The square root of 16200  is 90\sqrt{2}.

3. Same as before, we use the Pythagorean Theorem. This time, we're calculating b instead of c. This means we have to do 60^2-29.4^2=b^2, which gives us 3600-864.36, which equals 2735.64. We can put this in decimal form, which would give us 52.303...

4. This one, we do 15^2-9.5^2, which would give us 134.75. Simplifying this would give us 11.608....

Hope this helped! Just remember the Pythagorean Theorem.

Given that c=9, b=15, and C=29 degrees, find the measure of angle B
raketka [301]
Use the Sine Rule:-

b / sin B = c / sin C

15 / si n B =  9 / sin 29

sin B = 15* sin 29  / 9 =  0.8080

B =  53.90 degrees
