You didn't supply any expressions, but it'd be one of these (assuming it's unique combinations, rather than the duplicate permitting permutations):
(15!)/(7!(15-7)!)
or
(15!)/(7!8!)
or
(15•14•13•12•11•10•9)/(7!)
or
(15•14•13•12•11•10•9)/(7•6•5•4•3•2)
or
32432400/5040
or
6435

depending on what it has as possible answers.

xz_007 [3.2K]
<span>Let opposite ray be drawn for the base side ray of the given angle. This gives angle 180° between these two rays. Angle bisectors of the given angles 50°, 90°, and 150° make respectively half of these angles : 25° , 45° and 75° with the base ray. Then measure of the angles between the bisectors of the given angles and the drawn opposite ray are 180°-25°=155°, 180°- 45° =135° and 180°- 75° = 105° respectively.</span>

5h+4+52+64=180 what does that equal to
Softa [21]

Answer:

x=12

Step-by-step explanation:

5x+4+64+52=180

We move all terms to the left:

5x+4+64+52-(180)=0

We add all the numbers together, and all the variables

5x-60=0

We move all terms containing x to the left, all other terms to the right

5x=60

x=60/5

x=12
