Answer:
5 units
Step-by-step explanation:
Given h is the height, H is the hypotenuse and A is the base angle,
then Sin(A) = h/H
so h = HSin(A)
1.
A. This statement is wrong because the prediction is valid, not valid.
B. Refer to A.
C.This statement is valid, yet explains the prediction incorrectly.
[D.] This statement is correct because 50 x 6 = 300, therefore 20% of 300 is 60.
2.
A. This is incorrect because it equals 125%
B. This is also incorrect, it equals 12.5%
C. Refer to B
[D.] This is correct, it equals 1.14%, which is less than 1.25%
Answer:
x ≤ 7.25
Step-by-step explanation:
1) 
≤ 
<u>Distribute</u> <em>5</em> through the parenthesis.
2) ≤ 
Move the <u>variable</u> to the left side and change it's sign.
3) 
≤ 
Move the <u>constant</u> to the right side and change it's sign.
4) 
≤ 
Subtract the <u>like terms</u>.
5) 
≤ 
Divide both sides of the inequality by <em>-2</em>.
6) 
≤ 
A is congruent
B is congruent
C is congruent
D is not congruent
And E is the same picture as B so it is also congruent
