At max a rotation can be equal to π or 180°
So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise
Supplementary angle=180-110=70°
70° rotation clockwise
Answer:
$156.86
Step-by-step explanation:
$136.40 + 15% = $20.46
$136.40 + $20.46 = $156.86
Answer:
D 22.5CM
Step-by-step explanation:
A triangle that has an angle that measures 90 degrees would be a Right Triangle.
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
