Answer:
o = 54
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The definition of a linear pair tells you the two angles of a linear pair total 180°. Together, these relations tell you that an exterior angle of a triangle is equal to the sum of the remote interior angles.
In this geometry, the angle marked 78° is exterior to the left-side triangle. That means ...
78° = o° +24°
o° = 78° -24° = 54°
The value of 'o' is 54.

<em>Additional comment</em>
n° is the supplement of 78°, so is 102°.
m° is the difference between 102° and 22°, so is 80°.
A) Divide the total height by the average height:
26.4 / 1.2 = 22 total boys.
B) Divide total feet by total time:
440 feet / 20 seconds = 22 feet per second.\
Because the submarine is diving the rate would become negative 22 feet per second.
50m as a percentage of 5km is 1%.
50m in meters is 50
5km in meters is 5000
50m is 1% of 5000m
I hope this has helped you. :)
F(x) = (2x-3)(x-4)(x+3)
x-intercept, let f(x) = 0
0 = 2x-3
3 = 2x
x = 3/2
—
0 = x-4
x = 4
—
0 = x+3
x = -3
Therefore the 3 x-intercepts are (3/2,0) , (4,0) and (-3,0)
