What is the measure of angle B in the triangle?
pentagon [3]

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

How to solve mean media and mode
stiv31 [10]
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 :-)
