Answer:
A. 50
Step-by-step explanation:
Sum of interior angles of a triangle is always =180 °
Since this is a right triangle, therefore we know that one angle of the triangle measures 90°
Therefor sum of other two angles has to be =
One angle measures = 40°
Therefore the missing angle 

6 - b/3a a = 10, b = 9
6 - 9/(3*10)
6 - 9/30
6 - 3/10
6 - 0.3

You would do 196 divided by 1/2. You would get: 392
Answer: 31
Step-by-step explanation:
2^x=2 000 000 000
log2^x=log2 000 000 000
xlog2 = log 2 000 000 000
x= log (2000 000 000)/log 2
x= 30.897352854
round to 31
