Answer:
c
Step-by-step explanation:
there is an endpoint at A and the line continues on after g
Well, first what is 6-3=3 so now whats 3-2? 3-2=1
6-3=3-2
<span>Using trigonometry formula: sin a = cos (90 - a)
</span>cos (2x + 8) = sin (x + 37)
cos (90 - x - 37) = cos (53 - x)
Property of cosine function: (<span>2x + 8) = ± <span>(53 - x<span>)
2x + 8 = 53 - x
3x = 45
x = 15°
2x + 8 = -53 + x
x = -61°
Answer: x = 15°, x = -61°</span></span></span>
Answer:
Lacrosse = 62 students
Swimming = 62 students
Soccer = 124 students
Football = 186 students
Step-by-step explanation:
Based on the information, we can draw some equations
<em>1.</em> Lacrosse = Swimming
<em>2.</em> Soccer = 2 * Lacrosse
<em>3.</em> Football = 3 * Swimming
<em>4.</em> Football + Soccer + Swimming + Lacrosse = 434
Lets solve for once sport at a time, I will start with Football.
I will put equation 1, 2 and 3 into equation 4
3Sw + 2L + L + L = 434
We can now again put equation 1 into the new equation 4
3L + 2L + L + L = 434
Simplify
7L = 434
L = 434 ÷ 7
L = 62 students
Since L = Sw, 62 students did swimming also
We can put L into equation 2 to solve for So
So = 2 * 62
So = 124 students
And now we can put Sw into equation 3 to solve for F
F = 3 * 62
F = 186 students
66.7 is the answer i believe
