Answer:
- Option B for both questions
Step-by-step explanation:
<h3>Question 1</h3>
Select a pair that has two angles and the included side marked
- Option A - SAS
- Option B - ASA
- Option C - SAS
- Option D - Not enough information
<u>Correct choice is B</u>
<h3>Question 2</h3>
<u>Given</u>
- Rectangle KLMN with the area of 20 and coordinates of M(0, 0) and N(5, 0)
Rectangle area is the product of its sides.
Side MN is 5 as per difference in x- coordinates.
The other side has length of 20/5 = 4 units.
Side KL is side MN elevated 4 units up.
So the point L has coordinates (0,4) and K has coordinates of (5, 4)
<u>Correct choice is B</u>
Answer:
25%
Step-by-step explanation:
We can use a proportion to answer this question:
64 represent the 100% of the games
so:
x : 100 = 16 : 64
x = (16*100)/64 = 1600/64 = 25%
