1. OK, we want csc A, which is 1/sin A. When we have a right triangle whose hypotenuse is the square root of two times the side, we're where the Pythagoreans were twenty five hundred years ago when they realized the diagonal of the unit square was incommensurate with the side.
In other words we have an isoceles right triangle, 45 degree angles,
and
. So
so
fourth choice.
2. AC adjacent to 23, C is a right angle because 23+67=90. We have hypotenuse AB, so
, choice four.
3. The cosine is adjacent over hypotenuse.
The sine is opposite over hypotenuse,
First choice
Multiplying decimals:
First, multiply like a normal number.
64 × 37 = 2368
Add up the number of decimal points from your original numbers to find out where you should put the decimal point on your result.
6.4 has one decimal place, and -3.7 has one decimal place.
Our result should have two decimal places. (1+1)
23.68
Because we multiplied by a negative number, our result should be negative, too.
-23.68
The first one is (4,4)
and the second one is (0,4)
Have a good day!!!
871 rounded to the nearest tenth is 870
Answer: 60%
Step-by-step explanation: 36/60 of the jerseys are medium, so simplifying this fraction to 18/30, then 9/15, then 3/5, we see that 3/5= 60%.
