Answer:
m∠B = 
.
Step-by-step explanation:
Since the three sides of the triangle are given, then we apply cosine rule.
= 
+ 
- 2ac Cos B
But, a = 660 cm, b = 680 cm, and c = 100 cm.
So that;
= 
+ 
-2(660 x 100) Cos B
462400 = 435600 + 10000 - 132000 Cos B
462400 = 445600 - 132000 Cos B
132000 Cos B = 445600 - 462400
= -16800
Cos B = 
= -0.1273
B = 
-0.1273
=
Thus, measure of ∠B is .
72 Divided by 32 is equal to 2.25, but you can't have one fourth of a run, so you would round it to the nearest run being three. The answer is Three runs per game.
Answer:
cos Θ / sin² Θ
Step-by-step explanation:
csc Θ cot Θ =
= 1/sin Θ × cos Θ/sin Θ
= cos Θ / sin² Θ
So -x-3>-1
add x to both sides
-3>-1+x
add 1 to both sides
-2>x
so x is any number less than -2 but not including -2
