Answer: Okay I think D is the answer
Step-by-step explanation:
The first term is -43.
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.
Answer: m<KHL = 37 degrees.
m<GHK = 53 degrees
Step-by-step explanation:
<CHD and <KHL are vertical angles. They are equal in measure. m<CHD is 37 degrees, so m<KHL is also 37 degrees.
Notice <GHL is a 90 degree angle (because the lines that form it are perpendicular) and <GHL is made up of two angles: <GHK and <KHL.
m<GHK + m<KHL (37) = m< GHL (90 degrees)
Subtract 37 from both sides.
m<GHK = 53 degrees
The correct answer would be a length of 12 meters long
