Answer:
40° D. is your answer to this question
Answer:
<em>m∠1 = 90°</em>
<em>m∠2 = 35°</em>
<em>m∠3 = 55°</em>
Step-by-step explanation:
Find the diagram attached
From the diagram:

Given that <4 = 35°

The sum of the angle on a straight line at point A is 180°. Hence:

The sum of angle in the triangle ABC is 180°, hence;

Answer:
D. 14x - 4
Step-by-step explanation:
P = 2(L + W)
P = 2(4x + 5 + 3x - 7)
P = 2(7x - 2)
P = 14x - 4
If the problem says "space", that usually means that they are talking about volume. The maximum length the box can be is 8.4 inches. To find volume, you do length * width * height. You know the length and height, as well as the volume. You can replace the width with "x". Your equation should be:
11.5 * 8.4 * x = 272.8
Then you can just solve for x by dividing both sides by (11.5 * 8.4). The answer should be about 2.82 inches.
