Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50
Hope that helps :)
Answer:
are there any answer choices?
Okay so first, area is length times width, so 1/4x*x would be first = 1/4(x^2)=64. Then area or x = 16 or -16
perimeter would be width times two plus length times two. I recommend using math papa to calculate these numbers.
For each child she spent $5 plus $15 = $20
120 divided by 20 = 6 subscriptions
Answer:
a. yes
b. Q
c. line MP
Step-by-step explanation:
a. "Collinear" means "on the same line". The diagram shows point K on the same line with M and P, so ...
yes, M, P, and K are collinear
__
b. N, W, and U are the corners of face NUWQ, so point Q is also in that plane.
__
c. The plane MPQ includes face MPQN. The plane TVP includes face TVPM.
Line MP (or PM) is the line where these planes intersect.
