Answer:
x = 4
Step-by-step explanation:
17x-8=60 (this is an equilateral triangle, therefore all the angles should be 60 degrees)
17x-8=60
+8 +8
17x=68
/17 /17
x=4
Yes it’s still a line segment. The shape didn’t change in size.
Answer:
14,15,16
Consecutive number are numbers who's difference is 1.
Composite numbers are those numbers which are not prime.Hence thre consecutive composite numbers are 14,15,16..
Answer:
D. 65
Step-by-step explanation:
First, I found the hypotenuse. Using the pythagorean theorum, you would get ≈14.3 as the length of the hypotenuse.
Then, you want to find either the sine, cosine, or tangent of x.
sin(x) = .9091 -- opposite/hypotenuse (13/14.3)
cos(x) = .4196 -- adjacent/hypotenuse (6/14.3)
tan(x) = 2.1667 -- opposite over adjacent (13/6)
Then, choose any one of those (I chose sine) and do its inverse on your calculator.
sin^-1(.9091) = 65.38127....
Rounded to its nearest degree would be 65 degrees.
It seems like a long process but honestly, it's just calculator work. If you have a TI-84, you would press the 2nd button then SIN, COS, or TAN to get the inverse. Don't forget to make sure your calculator is in degree mode!
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
