Answer:
X = 30
Step-by-step explanation:
1) Y + X = 88
2) 58 + X = 88
-58 -58
------------------------
X = 30
You have 8 people, you have 2 groups of 4.
8!/4!4!
=(8*7*6*5*4*3*2)/(4*3*2*4*3*2)
=(8*7*6*5)/(4*3*2)
=7*6*5/3
=7*2*5
=70
It's been a few years since I've done this. If you haven't learned how to do this type of an equation yet, then I'm probably wrong.
11-2×48= 412. So the value of the expression is 412.
Answer:
<h2>x = 10√3</h2>
<u>Step-by-step explanation:</u>
cos 45° = base / hypotenuse
1/√2 = base / 15√2
15√2 = base√2
Base, = 15
sin 60° = perpendicular / hypotenuse
hypotenuse = x
√3/2 = 15 / x
x √3 = 30
x = 30 / √3
x = 10√3
