Answer:
I am 90% sure that the answer is M'N'O' is 90*
Step-by-step explanation:
A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?
Answer:
500%
Step-by-step explanation:
We find the volume of pyramid A
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.
Volume = a² h/3
Where a = 9 in
h = 10 in
Volume = 9² × 10/3
Volume = 270 cubic inches
Pyramid B has a volume of 1,350 cubic inches.
Step 2
We compare both volumes
Pyramid A : Pyramid B
270: 1350
= 270/ 1350
= 1 /5
Hence, Pyramid B is 5 times bigthan ger pyramid A
In percent, it is the volume of Pyramid B 500% bigger than Pyramid A
Whoah that's complicated i don't think i can help srry <span />
Answer:
cos theta = -4/5.
sec theta = -5/4.
tan theta = 3/4.
cot theta = 4/3.
Step-by-step explanation:
sin^2 theta + cos^2 theta = 1
(-3/5)^2 + cos^2 theta = 1
cos^2 theta = 1 - 9/25
cos^2 theta = 16/25
cos theta = -4/5 (negative because it is in Quadrant 3).
sec theta = 1 / cos theta = -5/4.
tan theta = sin theta / cos theta = -3/5 / - 4/5
= -3/5 * -5/4
= 3/4.
cot theta = 1 / tan theta = 4/3.
I have no idea i’m struggling my self
