Answer:
39 degrees
Step-by-step explanation:
It is shown that there is a 90 degree angle one part is given so 90-51=39 degrees.
Answer:
22°
Step-by-step explanation:
if is a right triangle than has a 90° angle
we are given another 68° angle
and we know the sum of angles in a triangle is 180° so
180-90-68 = 22°
Answer:
The equation of the line containing (4,2) and (3,5) in the slope-intercept form will be:
Step-by-step explanation:
Given the points




We know that the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
substituting m=-3 and the point (4, 2) to get the y-intercept i.e. b

2=(-3)4 + b
2 = -12 + b
b = 2+12
b = 14
Now, substituting b=14 and m=-3 in the slope-intercept form to determine the equation of a line in the slope-intercept.

y=(-3)x+(14)
y=-3x+14
Thus, the equation of the line containing (4,2) and (3,5) in the slope-intercept form will be:
The rocket will reach the ground after 4 seconds
Step-by-step explanation:
- Step 1: Find the time when the water rocket reaches the ground.
When the water rocket reaches the ground, the height, h will be zero.
⇒ h = 20 - 5(t - 2)²
⇒ 0 = 20 - 5(t - 2)²
⇒ 5 (t - 2)² = 20
⇒ (t - 2)² = 4
⇒ t - 2 = √4 = 2
∴ t = 2 + 2 = 4 seconds
