Answer:
C and D
Step-by-step explanation:
Because the relationship in a 30 60 90 triangle is , we can set JL to 1, KL to 2, and JK to √3. With this we can find the relations between the sides.
Answer:
These types of questions are not daunting if you break it down. First look at "Five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Next, analyze the second part. "Three times the quantity of four more than one half the number."
Looking at "Three times the quantity" simply means "3 times something".
"the quantity of four more than one half the number" is 4 + "one half the number" or 4 + (1/2)x.
So the second part is simply 3(4+x/2).
Finally we finish the entire equation, (2x-5) = 3(4+x/2) then solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x=34
Checking the left side, (2x-5) = 2(34) - 5 = 63.
Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.
Your answer would be B 35 degrees
Area is base x height
4x2=8 cm
Answer:
40 minutes
Step-by-step explanation:
Range = the highest value - the lowest value
= 45 mins - 5 mins = 40 mins
