Answer:
D 26
Step-by-step explanation:
154+154=308
308-360=52
52 divided by 2
=26
Given:
The points are (-3, 2) and (2, -13).
To find:
Slope-intercept form of the equation.
Solution:
Here 
.
Slope of the line:
m = -3
Using point-slope formula:
Add 2 on both sides.
Slope-intercept form of the equation is y = -3x - 7.
Answer and explanation:
We know the sum of interior angles in a triangle is 180°.
- 1 : 2 : 3 = 6 (1 + 2 + 3)
- x : y : z = 180 (x, y and z are the unknown angles)
To get from 6 to 180, we multiply by 30. This means we can find the angles by doing:
- 1 × 30 = 30°
- 2 × 30 = 60°
- 3 × 30 = 90°
The triangle must be right-angled because one of the angles is 90°. We know that the shape is a triangle because 30 + 60 + 90 = 180°.
The ratio is 30 : 60 : 90.
Hope this helps!
