Answer:
There are three major trignometric ratios in mathematics and they are:
sine(sin), cosine(cos) and tangent(tan). A popular acronym is used in recalling the formula for each ratio and it is: SOH-CAH-TOA.
Sine(x) = Opp/Hyp
Cosine(x) = Adj/Hyp
Tangent(x) = Opp/Adj
Now, the Hyp is the hypothenus of the triangle and it is the side opposite to angle 90. The opposite and adjacent is kind of relative depending on the angle been considered. For this case, we are considering angle 30 which the opposite side is 60 and the remaining side becomes the adjacent
Step-by-step explanation:
tan 30 = 60/x
Answer:
(2,6)
Step-by-step explanation:
Option:B
The triangle is rotated 90 degree clockwise around the point (0,0). The point is (-6,2) is made to rotate. The image so formed is at the point (2,6).
Answer:
7%
Step-by-step explanation:
The percentage increase is found as ...
increase/original × 100%
= (33170 -31000)/31000 × 100%
= 2170/31000 × 100% = 7%
Sarah's increase would be 7%.
You can put this into a calculator
But the answer is 160920
The equation for line AB would be x = -5 but It looks like it is asking for line AD.
The equation of line AD can be written in slope-intercept form y=mx+b, m being the slope and b the y intercept.
The y intercept would be point D since it is on the y axis. The y intercept would be (0,6) or 6 in the equation.
The slope can be calculated by the slope formula which is m = y2-y1/x2-x1
For the slope form we have to plug in both points A and D
6-1 over 0+5 y x
The slope is y/x and 6-1=5 and 0+5=5. This means that the slope is 5/5 or just 1. Now that we have the slope, we can form the equation y=x+6.
Since we have to turn it into standard form, we move x to the other side of the equation using Subtraction property of equality to get as the final answer
-x+y=6
