D. 54° as you know an external angle has to equal up to 360
when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer
Answer:
it will be B) 6/5 because thats the only thing that would get you a greater number then 2/3
Step-by-step explanation:
Calculating surface area
Big Prism-
7*14*2=196
7*21*2=294
14*21*2=588
196+294+588=1078
Small prism
3*6*2=36
3*9*2=54
6*9*2=108
36+54+108=198
1078:198
Simplify(divide by common factors)
(Divide2)
539:99
(Divide 11)
49:9
C is your answer
Answer:
x=27
∠JLK=2x+1=2(27)+1=55
Step-by-step explanation:
∠A+∠K=180
3x+13+∠K=180
∠K=167-3x
∠K+∠L+∠J=180
167-3x+39+2x+1=180
207-x=180
x=27
∠JLK=2x+1=2(27)+1=55
Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.
Completing order of operations is the correct answer.
