The answer is D because and obtuse angle is 91 degrees or more
Recall:
The
tan of the measure of an angle is the ratio of the opposite side to the adjacent side to that angle, that is :
.
Since this ratio is 3/y, we denote the opposite side, and adjacent side respectively by 3 and y.
(Technically we should write 3t and yt, but we try our luck as we see y in the second ratio too!)
Similarly,
.
The adjacent side is already denoted by y, so we denote the length of the hypotenuse by z.
Now the sides of the right triangle are complete.
Answer: A
1) 4, because 4/5 is closer to 4 than it is 3 1/2.
2) 100
3) 5
1 hours to fill the dish
for 1/2 of the dish
think
1/2 times 2=2/2=1 so therefor it takes 1 less doubling so
60 mins
1 less double
(double is 6 mins so )
60-6=54
the answe ris 54 mins or a
