Answer:
x = 2
Step-by-step explanation:
Altitude - on - Hypotenuse theorem
An altitude drawn to the hypotenuse of a right triangle, then
x² = 4 × (4 + 9) = 4 × 13 = 52 ( take square root of both sides )
x = 
= 
= 
× = 2
Answer:
4.5 cups flour
Step-by-step explanation:
6.5 - 2 = 4.5
699 is closet because as you subtract every number from 750, the smallest answer given is the closest to the number you started with.
Answer:
300 seconds
Step-by-step explanation:
First, you have to know how much half a minute is. Half a minute is 30 seconds.
Second, you multiply 30 by 10 because he answered 10 questions.
30 * 10 = 300
So your answer is 300 seconds
Lastly, have a great day! :)
Answer:
Y = 15sqrt(3)/4
Z = 15sqrt(3)/2
b = 45/4
Step-by-step explanation:
Sin(60) =Z/15
sqrt(3)/2 = Z/15
Z = 15sqrt(3)/2
Sin(30) = Y/Z
½ = Y/Z
Y = ½(15sqrt(3))/2 = 15sqrt(3)/4
Cos(30) = b/Z
sqrt(3)/2 = b/Z
b = 15sqrt(3)/2 × sqrt(3)/2
b = 45/4
sqrt is square root/radical
