Find the value of each variable
kondaur [170]

Answer:

The correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Step-by-step explanation:

Points to remember

The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2

<u>To find the value of variables</u>

From the figure we can see 2 right angled triangle with angle 30, 60 and 90

we get, d= 5 then b = 5√3

b = 5√3  the c = 5√3 * √3 = 15

and a = 2 * 5√3 = 10√3

Therefore the correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

What is the surface area of a tennis ball with a diameter of 6.7?? With full work please.
Sedbober [7]
So the formula you have to do is A= (pie)(radius)(squared)


divide 6.7 by 2 to find the radius which is 3.35


now do 3.35 * 3.35 ( we are squaring it) which = 11.225

now 11.225 times PIE is 35.264377537


so the answer is 35.264377537

hope that helped!

There are seven roads that lead to the top of a hill. How many different ways are there to reach the top and come back (you don'
Rainbow [258]

Answer:

49 different ways

Step-by-step explanation:

If there are seven roads that lead to the top, you have seven possible choices to go to the top of the hill.

Then, to come back to the start, you also have seven possible choices (seven roads), and you can pick any road.

So, if you have seven ways go to up and seven ways to go down, the number of different ways of going to the top and come back is the product these numbers of possible choices.

N(total) = N(up) * N(down)

N(total) = 7 * 7

N(total) = 49 different ways
