Answer: Angle B measures 70 degrees
Step-by-step explanation: One angle is given as 40 while the other two angles are yet unknown.
Remember that the sum of the interior angles in a triangle equals 180 degrees. In other words
Angle A + Angle B + Angle C = 180
Therefore
40 + (2x - 30) + (x + 20) = 180
40 + 2x - 30 + x + 20 = 180
By collecting like terms we have
40 - 30 + 20 + 2x + x = 180
30 + 3x = 180
Subtract 30 from both sides of the equation
3x = 150
Divide both sides of the equation by 3
x = 50
Having calculated x = 50 we can now compute the value of angle B as follows;
When x = 50,
2x - 30 becomes
2(50) - 30
= 100 - 30
= 70.
Angle B measures 70 degrees
1 gallon= 16 cups
1=16 2=16 3=16 4=16
16*4=64
You can solve mean by adding up all the numbers then dividing it by the number of numbers there are.
You can solve the median by putting all of the numbers in order and then crossing off one in the beginning then crossing off one at the end. You can continue that until you get to one number in the middle.
You can solve the mode by looking for the most frequent number. That's the mode. You can remember that by looking at the MO and remember most often.
I hope this helps :-)
