Answer:
x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.

Then inverse operation,

After to get a, b, and c you just need to plug in x.

Answer:
a = 33 degrees, b = 147 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees, and to solve for the angle on the other side of 109 degrees is 71 degrees, so to solve for a, have 180 minus 71 and 76. Then the sum of 71 and 76 is angle b since its the result of a subtracting from 180.
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.
