Answer:
b. angle K is acute
Step-by-step explanation:
We're often told not to draw any conclusions from the appearance of a figure in a geometry problem. Here, angle K appears to be somewhat less than 90°, so angle K is acute.

<em>Additional comment</em>
This choice of answer is confirmed by the fact that the other two (visible) choices say the same thing. If one of them is correct, so is the other one. Hence they must both be incorrect. (An obtuse angle is more than 90°.)
Interior angles of a triangle, when added, = 180
so < A + < B + < C = 180
41 + 90 + < C = 180
131 + < C = 180
< C = 180 - 131
< C = 49
< C + < D + < E = 180.....because when added they form a line
49 + 32 + < E = 180
81 + < E = 180
< E = 180 - 81
< E = 99 <======
Answer: 180 feet
Equipment depth:
5 x 17 = 85
5 x 19 =95
95 + 85 = 180
Miner depth:
17 feet per second x 19 seconds = 323 feet
Answer:
$14.45
Step-by-step explanation:
15% of 17 is 2.55. 17 - 2.55 is 14.45
