Answer:
22 students
Step-by-step explanation:
218 students - 20 students = 198 students on buses
198 students / 9 buses = 22 students per bus
It's HL because
there are two right triangles ABD and BCD
1) hypotenuses are equal (it is given that BD=AC)
2)Triangles have common leg so it is equal for both triangles
Answer: HL
Answer:
x=7.12
Step-by-step explanation:
This is a trigonometry problem so you would use sin cos or tan. and in this case we need to use sin.
An acronym I use to help me remember is is sohcahtoa
so sin= opposite / hypotenuse
and that means sin(22)= x/19
we then plug in sin (22) in out calculator and get around .37
then we can use algebra and multiply .37 by 19 to get our x value
.37(19)=x
x=7.12
Let us assume the bigger number = x
Then the smaller number that we get = x/7
Now it is given in the question that we have to subtract the smaller number from the bigger number and the result is 18. Based on this information, we can create an equation
(x/7) - x = 18
(x - 7x)/7 = 18
-6x/7 = 18
-6x = 18 * 7
-6x = 126
-x = 126/6
-x = 21
x = -21
Now putting the value of x in
x/7 = - 21/7
= -3
Then the two numbers are -21 and -3.
