Answer:
23°
Step-by-step explanation:
Let the interior angles of ΔABC be referenced by A, B, and C. The definition of point D means that ΔDAB is an isosceles triangle, so we have the relations ...
A + B + 118 = 180 . . . . interior angles of ΔABC
A = B +16 . . . . . . . . . . base angles of ΔDAB
Using the expression for A in the second equation to substitute into the first equation, we get ...
(B+16) +B +118 = 180
2B + 134 = 180 . . . . . collect terms
2B = 46 . . . . . . . . . . . subtract 134
B = 23 . . . . . . . . . . . . divide by 2
m∠ABC = 23°
Answer:
y= 704.5x - 409
Step-by-step explanation:
Complete question is : . Complete the equation for the relationship between the altitude and number of hours.
SOLUTION
By plotting altitude on y-axis and time or duration of travel on x-axis of the graph, we will have the the location of Nour at t = 0 will be represented by (0, -409)
when t = 2 hours location points will be at (2, 1000).
As you know, at a constant rate her altitude is increasing , we will have a linear graph with equation y = mx + b --> eq(1)
Slope of the line is given by:
m= (y-y') / (x-x') => (1000+409)/(2-0)
m= 704.5
y-intercept 'b' is -409
Therefore, the eq(1) will become
(1)=> y= 704.5x - 409
Where, 'y' represents Nour's altitude(in meters) relative to sea level after 'x' hours
The probability of correctly rejecting the null hypothesis when the null hypothesis is false is the power
<h3>How to complete statement?</h3>
From the question, we have the following highlights
- Null hypothesis is false
- Null hypothesis is correctly rejected
The statement that represents the probability of the above highlights is power
Hence, the statement that completes the blank is power

The triangle area is 7*2/2 = 7.
The volume is the triangle area times the side length, so 7*18 = 126 cm3
