The smaller the length u can figure out and if u can't put a small square in the cornorn
A. 2(2) = 4
B. 2(1)= 1+1
C. 2+ 67 = 1+ 68
Answer:
cosB = 21/75, tanB = 72/21
Step-by-step explanation:
Here, we can use pythagoras to figure out all sides. 75^2-72^2 = 21^2. So, we have sides with lengths 21, 72, and 75. We are given that sinB = 72/75. The definition of sin is opposite of hypotenuse. So, the opposite of angle B is side CA and the hypotenuse is BA. This allows us to find that BC is the 21 length side. The cos of an angle is adjacent over hypotenuse. In this case, it is BC/BA which is 21/75. similarly, Tan is opposite over adjacent or 72/21. And we are done. Those are the values. TO remember these, use the acronym:
SOH CAH TOA. S refers to sin and OH refers to opposite over hypotenuse. Similarly C is cos, A is adjacent, and H is hypotenuse, and then T is tan, o is opposite and A is adjacent.
If the number is rounded to 8,920,000 then it can't be over 8,924,999 and it can't be less than 8,915,000.
The numbers in the tens and hundreds are the least and the same. They might be zeros.
The thousands is 2x the ten thousands place. The ten thousands place now is either 2 or 1. The thousands place will either be 2 or 4.
The sum of all the digits is 24. We know that there will be an 8 and a 9 so if we add those up and subtract it from 24, we know the rest of the numbers need to add to 7.
8,924,001 would be your number.
