Step-by-step explanation:
$23.25 divided by $0.75 is 31.
Answer:
cos = 3/5
sin = 4/5
Step-by-step explanation:
tan=4/3 Q1
if you use Pythagorean theorem
Becauseof Q1
c=5
to picture
sin = 4/5
cos = 3/5
Answer:
The Pythagorean theorem should help you out. Since you already know two sides of the triangle, you can do a^2 + b^2 = c^2
So in this problem, 16.5^2 + 9.2^2 =
272.25 + 84.64 = 356.89
Pasty you would take the square root of 356.89 and you would get x = 18.89 or 18.9 rounded to the nearest tenth
You can check your work by the Pythagorean theorem once more. 16.5^2 + 9.2^2 = 18.9^2 and you should get the same approximate answer (it will be a little bigger because you rounded)
We know that a supplementary angle is 180 degrees because they add up to 180 degrees.
To solve for x:
Add the whole numbers
7x + 33 + 70 = 180
Subtract 103 on both sides.
7x + 103 = 180
-103 -103
Divide 7 on both sides to get x alone.
7x = 77
--- ---
7 7
x = 11
Check:
7(11) + 33 + 70 = 180
77 + 33 + 70 = 180
110 + 70 = 180
180 = 180
The angle
7(11) + 33
77 + 33
equals to
110
Which means that the angle is 110 degrees.
