Hello :
the terme general is : an = a1 +(n-1)d
a11 = a1+(11-1)×5
a11 = -12+50
a11 = 38
<span>the sum of the first 11 terms is : S11 = (11/2)(a1+a11)
</span>S11 = (11/2)(-12+38)
S11 = 143
Answer:
All pencils down, turn in your tests, put them in a stack on my desk" ordered the professor to the class of 200 students.
Almost every student put their pencil down except for one student who was adding to their last answer. When the other students had handed in their tests the late student walked up to the professor's desk.
"You failed" exclaimed the teacher. "You didn't put down your pencil in time and you have failed this test."
Suddenly the late student became indignant. "Do you know who I am?! DO YOU KNOW WHO I AM?!"
"Frankly, I do not nor do I care" the professor countered.
So the late student stuck his test into the middle of the stack of papers and walked out of the room.

Answer:
<u>M = 36</u>
Step-by-step explanation:
Since SAM = ZYX
We can assume that all angles on SAM will equal the same as ZYX.
There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.
Therefore M = 36°
