Answer:
65°
Step-by-step explanation:
The missing angle is x°
tan x° = 
tan x°= 
tan x° = 2.125
using a calculator:
- tan^(-1)(2.125) =64.79 ≈65°
The exact answer in fraction from is 2/15
The approximate answer in decimal form is 0.1333 (rounded to four decimal places)
The decimal value 0.1333 is equivalent to 13.33%
These are three ways to say the same basic answer.
===============================================
Explanation:
We have 4 red cards and 6 blue cards giving 4+6 = 10 total.
The probability of picking not blue (aka picking red) is 4/10 because there are 4 red out of 10 total.
If we don't replace the card we picked, then we have 3 red left over out of 9 total. The probability of picking red again is 3/9
Multiply those fractions
(4/10)*(3/9) = (4*3)/(10*9) = 12/90
Now reduce
12/90 = (6*2)/(6*15) = 2/15
note how the GCF 6 cancels
Using a calculator,
2/15 = 0.1333 approximately
The '3's after the decimal point go on forever.
