<span>We all know that the interior angles of a triangle sums up to 180</span>°. To get the missing angle, we simply subtract the sum of the given angles from 180°
<span>
Similar triangles have the same measure of angles.
Triangle 1: 80°, 62° </span>→ 180 - 80 - 62 = 38°<span>
Triangle 2: 62°, 38° </span>→ 180 - 62 - 38 = 80° SIMILAR TRIANGLES<span>
Triangle 1: 29°, 47° </span>→ 180 - 29 - 47 = 104°<span>
Triangle 2: 91°, 76° </span>→ 180 - 91 - 76 = 13° NOT SIMILAR<span>
Triangle 1: 100°, 45° </span>→ 180 - 100 - 45 = 35°<span>
Triangle 2: 25°, 45° </span>→ 180 - 25 - 45 = 110° NOT SIMILAR
Answer:
-0.5
Step-by-step explanation:
σM=σ/√N
=9/√36
=9/6
=3/2=1.5
Z=(x-μ)/σ/√N
=(19.5-24)/9/√36
=-4.5/1.5=-3
The probability that the sample mean will be larger than 19.5 = -0.5
P(>19.5)=P(Z>-3)= -0.5

its x<-2
What i've done is converted the exponential to a radical. I hope this helped. :)
Answer: The better estimate is 20cm.
