In a book about birds, there is a drawing of a sea eagle that shows a wingspan of 2.8 cm. If the book says the scale is 1:90, what is the actual wingspan of the sea eagle.
Answer:
2.52
The angle, its complement, and its supplement are 36, 54 and 144 degrees respectively
<h3>Supplementary and complementary angles</h3>
The sum of complementary angles s 90 degrees while that of supplementary angles is 180 degrees.
Let the complement of an angle be 90 -x and its supplement be 180 -x
If three times the measure of a supplement of an angle is eight times the measure of a complement of the angle, then;
3(180-x) = 8(90-x)
Expand
540-3x = 730 - 8x
540-720 = -8x + 3x
180 = 5x
x = 180/5
x = 36 degrees
Complement = 90 - 36 = 54degrees
Supplement = 180 - 36 = 144 degrees
Hence the angle, its complement, and its supplement are 36, 54 and 144 degrees respectively

Answer:
Thank you....... I guess
Step-by-step explanation:
Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
