Answer:
In order to tell if these are congruent triangles we would need to know if angles Y and V were congruent, angles X and W are congruent or if segments XU and WU were congruent.
Step-by-step explanation:
Any of these would work because you can use two different methods to telling that these are congruent triangles.
The first method is called side-angle-side. In it you need two side lengths that are congruent with a congruent angle in the middle. Since we already know that the right angle in the middle is congruent, and we know YU and VU are congruent, we would just need to know the additional side to prove congruence.
The second method is called angle, angle side. In this we need to know that two angles in a row are congruent followed by a side. Since we know the middle angle is the same, knowing either other angles would give us this method as well.
Answer:
Step-by-step explanation:
eq. of line is y-(-2)=-3(x-6)
y+2=-3x+18
y=-3x+18-2
y=-3x+16
∵(a,7) lies on it.
7=-a+16
a=16-7=9
a=9
Answer: Probability that a shopper buys shoes and a book is 0.02.
Step-by-step explanation:
Since we have given that
Event A : Buying a pair of shoes
Event B: Buying a book
Since A and B are independent events.
Probability that a shopper buys shoes i.e.
P(A) = 0.20
Probability that a shopper buys a book i.e.
P(B)=0.10
So, we need to find the probability that a shopper buys shoes and a book is given by

Hence, Probability that a shopper buys shoes and a book is 0.02.
Answer:
1 ft
Step-by-step explanation:
Look at it this way, 200:4 is equivalent to 50:1 in which the number 1 is how wide the building is in the model.
