Answer:
Step-by-step explanation:
<u>SOH CAH TOA</u>
Where:
s = sin
c = cos
t = tan
o = opposite
a = adjacent
h = hypotenuse
cos = 2/3 where 2 is adjacent side and 3 is hypotenuse, now find opposite side using a^2 + b^2 = c^2 //c is hypotenuse side
2^2 + b^2 = 3^2
4 + b^2 = 9
b^2 = 9 - 4
b^2 = 5
b = square root (5) = 5^(1/2) //opposite side
sin = O/H
//Hope it helps.
Answer:
Infinite solutions
Step-by-step explanation:
The two equations are the same, so therefore, any value of x will result in an output that belongs to both lines, if you understand what I mean.
Hope this helps :)
1.21 because of means multiply and .55% is .0055 so 220*0.0055 is 1.21.
For 90° clockwise rotation, (x, y) becomes (y, -x).
Your rotated point is (2, 3).
There would be 81 in grade 5
and 68 in grade 6
because 10% of 90 is 9 so 90 - 9 =81
and 15% of 80 is 12 so 80 - 12 = 68
