Answer:
135°, 63°, 63°, 99°
Step-by-step explanation:
Find attached the diagram used in solving the question.
We would use formula for sum of interior angles to get each exterior angle.
From the diagram, we added additional variables to be able to solve for sum of interior angles.
Sum of angle on a straight line = 180°
a° +15z° = 180°
b° +7z° = 180°
c° +7z° = 180°
d° +11z° = 180°
Where a,b,c and d are interior angles
Sum of interior angles = 180(n-2)
n = number of sides
For quadrilateral, n= 4
a°+b°+c°+d° = 180(n-2)
180-15z +180-7z+180-7z+180-11z = 180(4-2)
720-40z = 180(2)
720 - 360 = 40z
z = 360/40
z = 9
Each exterior angle:
15z = 15×9 = 135°
7z = 7×9 = 63°
7z = 7×9 = 63°
11z = 11×9 = 99°
If it takes a ball to roll 12 meters per sec, and asks how far it will roll for 3 seconds you would multiply 12 and 3 getting 36.
The ball will roll 36 meters for 3 seconds
Answer:
Step-by-step explanation:
Time is the independent variable here. The tank is being filled and the amount of water in it is dependent on how much time passes by.
This is a straight line function (linear function); the rate at which the tank is filled is:
750 m^3

Step-by-step explanation:
Leg 1 of left triangle = 8 units
Leg 2 = 6
Hypotenuse = 10 ( via Pythag theorem....or distance formula)
R triangle Leg1 = 8 units
leg 2 = 6 units
hypotenuse = 10 units so the triangles are congruent by SSS
distance from right angle of triangle 1 ( at 0,0) to
right angle of triangle 2 ( at 6,-3)
using<u> distance formula </u>
from 0,0 to 6, -3
d^2 = ( 6-0)^2 + (-3 -0)^2
d^2 = 45
d = sqrt 45
B.) 84
The reason why is because 6x14= 84
