Answer:
T₁₀
Step-by-step explanation:
We know the first term is 21, which is a
We work out the difference by taking 21 away from 42 which equals 21.
We then use the general formula:
Tₓ = a + (x-1)(d)
We need to find the term which equals 210
210 = 21 + (x - 1)(21)
210 = 21 - 21 + 21x
210 = 21x
x = 10
Hence it is the 10 term when the thing equals 210.
Answer:
Blank 1: 64° (or 32°, depending on what the label applies to)
Blank 2: 42
Step-by-step explanation:
It is a common mistake to believe you have solved the problem when you have found the value of the variable(s) in the problem. You have correctly found the values of n (42) and m (9). However, that is not what the problem is asking for.
We cannot tell if the value (1/2n+11)° is referring to angle DAB, or to angle CAB. In any event, (1/2n+11)° = (1/2×42 +11)° = 32°.
If that is angle CAB, then angle DAB is twice that value, 64°.
If that is angle DAB, then angle DAB is 32°.

The side length CD is the same as any other side length in a rhombus, so ...
CD = 4m+6 = 4×9 +6
CD = 42 . . . . units
Answer:
Yes, I believe the answer is C because that is the only one that sounds reasonable.
If it were any of the other answers than it would either be intersecting or on the exact line and it is supposed to be perpendicular mean never touching.
