Answer:
56
Step-by-step explanation:
The angular sum of a triangle is 180 and we know 2 angles so we just add them together and subtract that from 180 for the last angle measure.
90+34 = 124
180-124=56
The answer is B. 4/9 = 0.444444
Hello from MrBillDoesMath!
Answer:
The average is increased by 5
Discussion:
Let x be one number and y the other number.
Average of x,y = (1/2) ( x + y)
if, say, x is increased by 10 then the average of the numbers is
( ( x+ 10) + y) /2
= (x+y)/2 + 10/2 => (x+y)/2 is the average of the original numbers
= (x+y)/2 + 5
So the average is increased by 5
Thank you,
