M<6 is 60
Since AC and BD are parallel, <6 and <4 are supplementary.
supplementary means = 180 degrees
Since m<6 is 60 degrees, subtract 60 from 180 to get <4
180 - 60 = 120
M<4 is 120
hope this helps
87/150=0.58
0.58*100=58
$87 is 58% of $150
Good luck!
The correct answer is B) AC = BC
We know this because the two triangles are equal due to SAS
17²-8²=225
√225= 15
therefore both x and y are 15 ft
