7x + 7 = 112

-7

7x = 105

divide 7

x = 15

Now, for y.

Angle 112 and the unknown angle = 180*

This means the unknown angle = 68

4y = 68

divide 4

y = 17

4y+112=180 angle sum property
Therefore,
4y=180-112
= 68
As 4y=68 then y = 17

Now,
4y +7x+7=180 angle sum property
7x =180-68-7
7x=105
X=15

Which set of side lengths can be used to form a right triangle

leva [86]

Answer:

14, 48, 50

Step-by-step explanation:

To check which set of side length can be used to form a right triangle we use pythagorean theorem

c^2 = a^2 + b^2

biggest side (hypotenuse is c^2)

(a) 14, 48, 50

$50^2 = 14^2 + 48^2$

2500= 196+2304

2500= 2500 that is true

(b) 30, 40, 60

$60^2 = 30^2 + 40^2$

3600= 900+ 1600

3600= 2500 that is false

$60^2 = 14^2 + 50^2$

3600= 196+2500

2500= 2196 that is false

(d) 10, 24,28

$28^2 = 10^2 + 24^2$

784=100+576

784=676 that is false

So on and so forth.

The number of ways five time slots can be assigned is:

10×9×8×7×6 = 30240

Or, using permutation notation, ₁₀P₅.
