Step-by-step explanation:
my answer is in the image above
Answer:
19
Step-by-step explanation:
Cause it’s angle on a straight line which is equals to 180
Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant
So this question is arithmetic because it keep minus by 7
from 19 - 7 = 12
12 - 7 = 5
5 - 7 = -2
so common difference is -7
or you can check with arithmetic formular as
=
+ (n−1)d
I will just put in the 4th term which is -2 and n will equal to 4
and
is the 1st term which is 19
-2 = 19 + (4−1)d
-2 - 19 = 3d
d = ![\frac{-21}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-21%7D%7B3%7D)
d = -7
Answer:
B. <1 = 90, <2 = 40
Step-by-step explanation:
Given that ∆MLN = ∆QPR, it follows that the measure of their corresponding angles would be of the same measure.
<P = right angle = 90°
<1 corresponds to <P, therefore, <1 = 90°
<R = 40°
<2 corresponds to <R, therefore, <2 = 40°.
The answer would be: B. <1 = 90, <2 = 40
