Answer:
See image
Step-by-step explanation:
It helps a lot to draw a triangle. Sin is OPPOSITE/ HYPOTENUSE. You can use Pythagorean thm to find the third side. Then use cos = ADJ/HYP
tan = OPP/HYP
Then, find reciprocal functions. Reciprocal just means you are flipping the ratios over.
csc = HYP/OPP
sec = HYP/ADJ
tan = ADJ/OPP
The only tricky remaining part is that you cant leave a radical (the square root symbol) on the bottom of a ratio. So you have to fix those. See image.
Answer:
Step-by-step explanation:
In parallelogram opposite angles are equal
6x = 66 {Divide both sides by 6}
x = 66/6
x = 11
20y - 46 = 13y + 10 {Add 46 to both sides}
20y - 46 + 46 = 13y + 10 + 46
20y = 13y + 56 {Subtract 13y from both sides}
20y - 13y = 13y-13y + 56
7y = 56 {Divide both sides by 7}
y = 56/7
y = 8
The answer to this question would be 4
Answer:
m=0
Step-by-step explanation:
A general rule to remember is "rise over run" or m= 
To find the slope between these two pairs of points:
1. Choose one pair of points to be X1 and Y1 (it doesn't matter which)
In this case, let's use (-11,3) so X1 =-11 and Y1= 3
2. The second pair will be (14,3) so X2 = 14 and Y2=3
3. Applying the equation above:
It becomes: m= 
m = 
m = 0
