Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
The answer is whatever the other guy said
Answer:
The answer is: 7% ; 13% ; 0.15 ; 4/25 ; 21/100 ; 0.28
Yes, 50^x = 17 is an exponential equation with base 50, and the task here is to solve it for x.
1) Take the log of both sides: x log 50 = log 17
2) Divide both sides b log 50:
log 17
x = ----------
log 50
3) This last result can't be simplified, but can be evaluated"
x = 1.2304 / 1.6990 = 0.724 (approx.)
