Well this triangles angles have to add up to 180
If E is a perpendicular bisector with V so V= 90 degrees
and E=45 degrees
90+45=135 degrees
180 degrees -135 degrees =A) S = 45 degrees.
B) I conclude VES is a isoceles triangle because it has two corresponding angles.
C) This is a complicated one lets work this out in the comment section...
D) Same as C
0.319 rounded to the nearest hundredths is 0.32. Because 9 is over 5 which makes it round up.
Answer:
This may help but I think you mean cosine function it means
The cosine function is one of the basic functions encountered in trigonometry (the others being the cosecant, cotangent, secant, sine, and tangent). Let be an angle measured counterclockwise from the x -axis along the arc of the unit circle. Then is the horizontal coordinate of the arc endpoint.

Answer:
c = 1
Step-by-step explanation:
Given
9 = 2(c + 3) + 1 ← distribute parenthesis and simplify right side
9 = 2c + 6 + 1
9 = 2c + 7 ( subtract 7 from both sides )
2 = 2c ( divide both sides by 2 )
1 = c
