Answer:
Below
Step-by-step explanation:
● cos O = 2/3
We khow that:
● cos^2(O) + sin^2(O) =1
So : sin^2 (O)= 1-cos^2(O)
● sin^2(O) = 1 -(2/3)^2 = 1-4/9 = 9/9-4/9 = 5/9
● sin O = √(5)/3 or sin O = -√(5)/3
So we deduce that tan O will have two values since we don't khow the size of O.

●Tan (O) = sin(O)/cos(O)
● tan (O) = (√(5)/3)÷(2/3) or tan(O) = (-√(5)/3)÷(2/3)
● tan (O) = √(5)/2 or tan(O) = -√(5)/2
Answer:
what are you asking? Because I probably have the answer
I assume you mean 3*3*3*5*5 it would be 3^3 times 5^2. thats as simplified as i can make it. hope this helps! if anyone knows a better way to put these please post.
Answer:
the area is 30
Step-by-step explanation:
area of triangle =base×height
so ,
base=7.5
height=4
why , shouldn't we take 5(or)6 as height because we shouldn't take slanting lengths as height.
so apply base and height in the formula
7.5×4=30
please follow me
Answer:
216
Step-by-step explanation:
800 ÷ 100 = 8
8 = 1%
73 x 8 = 584
800 - 584 = $216
