Answer:
its B
Step-by-step explanation:
180° because it is half of a full circle(360°)
Answer: 7: 17
Step-by-step explanation:
This doesn't really make sense but it's how I do it
8:02 = 7:62
7:62
<u> - 45</u>
7: 17
the sum of the angles in a triangle = 180°, thus
x +
x +
x = 180
multiply through by 6
6x + 3x + x = 1080
10x = 1080 ( divide both sides by 10 )
x = 108
the angles are 108°, 54° and 18°
Since all the angles are different and the largest is 108°
The triangle is an obtuse scalene triangle
