Answer:
D
Step-by-step explanation:
D
Answer:
2544.8
Step-by-step explanation:
To find 4.5 radians in degress, multiply 4.5 radians by 180°π radians
4.5 x 180°π≈4.5*565.5=2544.75≈2544.8
Answer:
x=-29
Step-by-step explanation:
Minus 17 from both sides.
So x=-29
Answer:
Step-by-step explanation:
DEF is similar to CBA
because angle
angle C = angle D
angle B = angle E
angle A = angle F
The ratio is
10.8/5.4 = 9/4.5 = 6.4/3.2 = 2
Answer:
A
Step-by-step explanation:
Each coordinate of the triangle will have to dilate by 1/2 in order for the triangle to be fully dilated. Let's check each option to see which one has the correctly dilated points.
First, we'll look at A. A(4, 2) goes to A'(2, 1)... which is looking good so far! Half of 4 is 2, and half of 2 is 1, so the right dilation was applied. Next, let's check out B. B(-4, -2) goes to B'(-2, -1), which is still looking okay. Half of -4 is -2, and half of -2 is -1. Finally, we'll check the point C. If this one is correctly dilated, option A is the right option. C(2, -4) goes to C'(1, -2), and we can now be sure that option A is correct. Half of 2 is 1, and half of -4 is -2.
So, option A is the one to select. Hopefully that's helpful! :)
