Sin x =11.r
We know tan x = sin x divided cos x
If you plug in 11 instead of tan x and r for cos x you will have the answer
In similar triangles, the ratios of corresponding sides are equal.
This means
y/6=5/(4+5)
Cross multiply
y=5*6/(4+5)=30/9=10/3 (or 3 1/3)
If your question is to write it in scientific notation, it's 10^4 and the exponent is 4
Answer:
18/4
Step-by-step explanation: in order to get an equivalent ration just multiply both numerator and denominator by the same number
in this case I multiplied by 2 and got 18/4
