Answer:
5.6 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adj side
tan 34 = x / 8.3
8.3 tan 34 = x
5.59842 = x
To the nearest tenth
5.6 =x
No
Given 3 sides of a triangle, the sum of any 2 sides must be greater than the third side.
Consider the 3 given sides 1, 7 and 11
7 + 11 = 18 > 1
1 + 11 = 12 > 7
1 + 7 < 11 ⇒ not valid
Hence these sides do not form a triangle
Answer:
7.15 hours or 7 hours 9 minutes.
Step-by-step explanation:
Time = distance / average speed.
= 715 / 100
= 7.15 hours.
8 choose 3 = 8!/(3!*(8-3)!) = 8*7*6/(3*2) = 56
3/4b-1/6=1/2×b
1.75b=.3
b=0.2
I believe this is right. But not 100%
