Answer:
A plane shape with four straight sides and four right angles for corners is called a rectangle.
Step-by-step explanation:
The probability of drawing a black marble is 7/31 or .226 or 22.581%. To find the probability of these type of questions, add all together to get 31, then since there are 7 black marbles the probability would be 7/31.
Answer:
Same as Angle B. 90 degrees.
Step-by-step explanation:
If triangles are similar then they have the exact same angle measures. Angle m will have the same value as angle B. If angle B's measure is not found, then find it by adding angle A and angle C together and subtract from 180.
The picture is cut off but if A =60 and C=30 then 60+30=90 and 180-90=90. Angle B and M are both 90 degrees.
Step-by-step explanation:
4m =16
divide both sides by 4
m = 4
he has 4 model trains
