Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180
Answer: 99.73%
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Let X be the random variable that represents the data values.
Formula for Z-score : 
For x=94, we have
For x=106, we have
The probability that the samples are between 94 and 106:-
Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
Answer:
38 sq ft
Step-by-step explanation:
Add together the two triangles plus the rectangle area.
A(triangle1) = 1/2 bh = 1/2 4*4 = 8 sq ft
A(triangle2) = 1/2 bh = 1/2 4*3 = 6 sq ft
A(rectangle) = lw = 8*3 = 24 sq ft
A(total) = 8 + 6 + 24 = 38 sq ft
Your answer will be 2.181818
