Answer:
I believe the answer is option B because I am right. Haha trust me.
Step-by-step explanation:
Answer: 3173 mm² (Answer C)
Area of the bottom triangle = 1/2 x base x height
Area of the bottom triangle = 1/2 x 19 x 23 = 218.5mm²
Area of the top triangle = area of the bottom triangle
Area of the top triangle = 218.5mm²
Area of the 3 side rectangles = (23 x 38) + (19 x 38) + (30 x 38)
Area of the 3 side rectangles = 2736 mm²
Total Surface area = 218.5 + 218.5 + 2736 = 3173 mm²

Answer: Total Surface area = 3173 mm²

Answer: None of them cuz
Step-by-step explanation:
Answer:
Granted that uppercase letters are the angles measurements and lowercase letters are the side lengths. I also was unable to round as I don't know to what decimal you need to round to.
First to find the measure of angle B, we must subtract A and C from 180
B=54
Next, we can use the law of sines in order to find the measures of a and b
As a reminder, The law of sines is
First, lets solve for b
Next lets solve for a
For this case we must follow the following rules of rounding
1) If the previous number is greater than or equal to five, then the next number increases by one unit
2) If the previous number is less than five, then the next number stays the same
Therefore, the steps for rounding to the nearest tenth is:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
Rounding to the nearest tenth is:
5.6
Answer:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
5.6
