Answer:
Step-by-step explanation:
12²+16²=144+256=400=20²
so it is a right angled triangle.
let BC bebase and AB=height or perpendicular
AC=hypotenuse
sinC=12/20=3/5=0.6
cosC=16/20=4/5=0.8
tan C=12/16=3/4=0.75
similarly sin A=16/20=4/5=0.8
cos A=12/20=3/5=0.6
tan A=16/12=4/3≈1.33
Answer:
Answer should be D and E
Step-by-step explanation:
First, you need to figure out the radius of B.
As radius of A is 6 in, 20% of 6in would be 1.2in. So total radius of B = 6+1.2 = 7.2
Now you get the radius of B, calculate th area of B using the formula πr^2.
= π(7.2)^2 = 162.86 = area of B
Now, all answers except D and E is smaller than B. So, the answer would be D and E.
Answer:
The y-coordinates are the same.
Step-by-step explanation:
Since the y of (6, 9) and (6, -9) is different is because one of them has a positive y and the other order pair has a negative y.
