Answer:
10. 20.9°
11. 73.2°
Step-by-step explanation:
The inverse sine function is used to find the angle from its sine value.
<h3>10.</h3>
In each case, the equation is of the form ...
a/sin(x) = b/c
Multiplying both sides by c/b·sin(x), we find the solution is ...
sin(x) = ac/b . . . . . find sin(x)
x = arcsin(ac/b) . . . . . find the corresponding angle
For the given values a=7.2, b=13, c=sin(40°), we have ...
x = arcsin(7.2sin(40°)/13) ≈ 20.9°
<h3>11.</h3>
For the given values a=6.53, b=√40, c=sin(68°), we have ...
x = arcsin(6.53sin(68°)/√40) ≈ 73.2°
Answer:
Step-by-step explanation:
One solution: when two lines intersect in exactly one point.
Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.
No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.

Answer:
5
Step-by-step explanation:
This is a pretty simple question to answer, the one step that needs to be done is divide 78.5 by 15.7. You should come up with 5.
The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.
The sides of the triangle shown are AB and BC and the hypotenuse is AC,
so the correct answer would be:
(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169
