Answer:

x = 12

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

9^2 +x^2 = 15^2

81 +x^2 = 225

Subtract 81 from each side

81-81 +x^2 = 225-81

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12

Step-by-step explanation:

Length of an arc = tetha/360 × 2 × pi × r

Converting 7pi/4 to tetha

(7 × 180) / 4 = 315°, since pi = 180°

Plugging values to the formula:

315/360 × 2 × 3.142 × 1 = 5.498units

Hello can you please help me posted picture of question

irina [24]

We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2

$6C2= \frac{6!}{2!*4!} \\ \\ 
= \frac{6*5}{2} \\ \\ 
=15$

This means, there can be 15 different combinations of 2 members that can sit in the front row.

So, the answer to this question is option A

The lengths of the legs of a right triangle are 6 cm and 8 cm. What is the length of the hypotenuse?

Svetllana [295]

You require the Pythagorean Theorem: in a right triangle, the sum of the squares of the legs equals the square of the hypotenuse.In this case 6^2 + 8^2 = 36 + 64 = 100 = 10^2
the hypotenuse is 10.
