Question
solve the following oblique triangle:
a=134.2, b=84.54, B= 52 degree 9' 11"

Answer
Hi Diana,

Well, to solve this problem, you will have to use the law of sines and the law of cosines.

sinA = asinB/b so sinA = 1.25 and since sin of anything can never be greater than 1 angle A doesn't exist so there is no triangle in the world that fits the conditions you gave me. So the answer is: no such triangle.




I hope this helps,
Robi

Expertise

I can answer a variety of questions on mathematics. Questions on trigonometry, calculus(preferably single variable), algebra, geometry, and number theory will be answered. I cannot answer questions on abstract branches of mathematics such as group theory. I also cannot answer questions on statistics. In number theory, I can answer questions on congruences, prime numbers, units, functions, and the riemann-zeta function.

Experience

I have studied advanced math my entire life. I started calculus in sixth grade. I have attended numerous math competitions and I am attending math organizations such as the San-Diego math circle. Also, this year I have been invited to the USAMO which is a prestigious math competition (Every year the USAMO invites 500 students from across the USA to participate in this competition. The top 6 go to represent the USA in the International Math Olympiad).

Organizations
I am in the San Diego Math Circle

Education/Credentials
I am entering high school and have received a perfect score and the STAR test 5 times in a row. I also have gotten recognitions in the AMC 10, AIME, Math Counts, and ARML. Additionally, I have won the San Diego Math Olimpiad twice in a row.
