Answer:
D.
Step-by-step explanation:
If you look at the pattern, the first shape (square) has four sides. Then, you have 5 sides, and finally, 6 sides.
Thus, a pattern of 4, 5, 6. So, the next shape must have 7 sides, leaving the only possible answer as D.
Answer:
Step-by-step explanation:
1. Cos 52° = adj/hyp
Cos 52° = x/13
x = 13×cos 52°
x = 8.00
2. Sin70° = opp/hyp
Sin70° = 30/x
x sin70° = 30
x = 30/sin70°
x = 31.93
x ≈ 32
3. Tan∅ = opp/adj
Tan∅ = 45/51
Tan∅ = 0.8824
∅ = tan-¹(0.8824)
∅ = 41.42°
∅ ≈ 41°
Luckily you are not required to use a ruler or be exact- so it just has to be in the range. I would (in pencil or erasable color) divide the line into 4 sections as guide points then determine where each of the sections would go. EX: If it was 4/10 I know it is closer to the 1/2 mark then the 1/4 mark and place the dot.
If you need to, find where the marks would be before simplified-- 3/10's half way guide point isn't 1/2 its 5/10.
Answer: A. She substituted incorrectly into the distance formula
She should be subtracting x from x and y from y but she is subtracting y from x.
