Answer:
tan θ = (√13)/3
Step-by-step explanation:
cosθ = 3/√22 = adj/hyp
third side of triangle has dimension
c = √((√22)² - 3²) = √13
tan θ = opp/adj = (√13)/3
The smaller angle = 58
the larger angle = 122

8^2 is 64 and 8^7 is 2097152 and do 64*2097152 which is 134217728.
3/5 - 2/10=
Same denominator would be 10 so..
6/10-2/10= 4/10
4/10 simplified would be 2/5.
The answer is 2/5
