Answer:
58 ft.
Step-by-step explanation:
We will use trigonometry to find the distance.
We know that he is 29 ft above the ground (26, height of building, + 3, height of bird).
We use the angle 60 and we see that we have a known side which is adjacent to the angle. The side we are trying to find is the hypotenuse. We will be using cos because cos uses adjacent and hypotenuse sides of triangle.
cos60 = 29/x
cos60x = 29
29/cos60 = x
x = 58
He must fly 58 feet in order to get to the ground.
For blue marbles:
16 = 8 * 2 ( 8 groups with 2 marbles in everyone of them )
For white marbles:
8 = 4 * 2 ( 4 groups with 2 )
8 + 4 = 12
Answer:
The greatest number of groups Colton can make is 12.
Answer:
x = 21°
Step-by-step explanation:
opposite angles are equal
therefore, (3x + 1)° = 64°
open the brackets
3x + 1 = 64
3x = 64 - 1
3x = 63
divide both sides by 3
x = 21°
5.5x + 3 = y
7x =y
5.5x + 3 = 7x (-5.5x both sides)
3 = 1.5x (÷1.5 both sides)
X = 2
