Answer:
THEY START AT A DIFFERENT PLase sorry about all caps
Step-by-step explanation:
x = cos (47) = Pi/3, cos 47 = X/3
Step-by-step explanation:
x = 2.05, 2.05 (2.05)²
Answer:
No
Step-by-step explanation:
Here we are taking only one measurement: the height of one person. Strictly speaking, this is NOT a statistical question.
"List the heights of a sample of 50 first-graders" would definitely be a stat. question.
If there is a really short way of doing this, I don't see it. The only way I know to do it is to find the third angle of both triangles.
So for F the third angle for each of the pairs is
left side: 180 - (51 + 30) = 180 - 81 = 99
right side: 180 - (109 + 30) = 180 - 139 = 41
This is not the answer.
G
180 - (92 + 70) = 180 - 162 = 18
180 - (28 + 70) = 180 - 98 = 82
This is not the answer either.
H
180- (58 + 30) = 180 - (88) = 92
180 - (90 + 58) = 180 - 148 = 32
Not at all.
180 - (35 + 82) = 180 - 117 = 63
180 - (82 + 63) = 180 - 145 = 35
This pair has a third angle that is equal to the other triangle's pair. This is your answer.
Answer:
You just subtract 126 degrees from 180 degrees = 34 degrees for all angles
