We know that 0.8 is the same as 4/5. The reciprocal is basically a the denominator over the numerator. So in this case, the reciprocal of 0.8 would be 5/4
Answer:
b=h/G
Step-by-step explanation:
let's substitute h for 6, G for 3, and b for 2. you can also do this with the product of any two numbers (ie, 8,2, and 4 & 20,4, and, 5, etc.). so we have the equation 6=(3)2. to get 2 by itself we need to divide both sides by 3. so we get 6/3=2. now just plug the variables back in place of the numbers and you have b=h/G. hope this makes sense!
Cos B = c/a
cosine is adjacent over hypotenuse.
there is an acronym for this: soh-cah-toa
soh: sine is opposite over hypotenuse
cah: cosine is adjacent over hypotenuse
toa: tangent is opposite over adjacent
This is a backup question it would be great to state what question 3 was please
