Answer:
-5/13
Step-by-step explanation:
sin theta = opp / hyp
sin theta = -12 /13
we can find the adj side by using the pythagorean theorem
adj^2 + opp ^2 = hyp^2
adj^2 +(-12)^2 = 13^2
adj^2 +144 =169
adj^2 = 169-144
adj^2 = 25
Taking the square root of each side
adj = ±5
We know that it has to be negative since it is in the third quad
adj = -5
cos theta = adj / hyp
cos theta = -5/13
Answer:
840
Step-by-step explanation:
Last year, 800 students attended the career fair at West High School.
And, this year the number of students who attended the career fair increased by 5%.
We are asked how many students attended the career fair at West High School this year.
Therefore, the number of students attended the career fair at West High School will be ![800[1+\frac{5}{100} ] =800 \times 1.05 = 840](https://tex.z-dn.net/?f=800%5B1%2B%5Cfrac%7B5%7D%7B100%7D%20%5D%20%20%3D800%20%5Ctimes%201.05%20%3D%20840)

Answer:
B, C and D
Step-by-step explanation:
dilation is the only transformation that affects the size of the shape, and no transformations affect the shape of the figure.
Y-13=4(x-2)
y-13=4x-8
y=4x+5
