<DSR + <SRD + <RDS = 180° (Angle sum property)
2x + x +3x = 180°
6x = 180°
x = 180°/6
x = 30°
So, <SRD = x = 30°
<RDS = 3x = 3(30°) =90°
<DSR = 2x = 2(30°) = 60°
Hope it helps !

Jai hind !
and with that template in mind.
3 units down, D = -3
4 units to the right, C = -4
f(x) = (x - 4)² - 3
Answer:
Standard form:: Ax + By=C
Step-by-step explanation:
Answer:
parallel : (b) and (g)
perpendicular : (d) and (f)
Step-by-step explanation:
straight line equation : y = mx + c
Lines that are parallel have the the same gradient(m),
(b) and (g) are parallel, both of them has m= 1/2
Lines that are perpendicular will have the product of their
gradient(m) equal to -1. So, m1 × m2 = -1
(d) and (f) are perpendicular, because : -4 × ¼ = -1
Hope I was able to help:))
Answer:
It is not reasonable
Step-by-step explanation:
We have a population of 150 and the person takes 10 data from the raccoons, if we take the average of these values, we are left with:
(17 +19 +20 +21 +23 +27 +28 +28+ 28 + 32) / 10 = 24.3
Therefore the inference of the average weight is to approximate up to 25.
This is NOT correct, since it cannot be approximated in this way first and also that the sample is not representative. 10 sample data of 150, which is the population, will give results with a very large margin of error and with a minimum level of confidence.
Therefore it is not reasonable.
