Hello!
The slope-intercept form is: y = mx + b. In this form, m is the slope and b is the y-intercept.
Since we are given the slope, which is -1/2, and the y-intercept which is (0, -3/4). This means that the value of b is -3/4.
So therefore, the equation of the function is: y = -1/2x + -3/4.
All of them could be as A would be an equilateral B,C,D would be irregular triangles and 3 would be an Isosceles triangle but if you had to go with one it would be A
Answer:
46°
Step-by-step explanation:
When secants intersect each other and a circle, the external angle (A) is half the difference of the intercepted arcs:
∠A = (arcDC -arcBC)/2
12° = (arcDC -22°)/2 . . . . . . . fill in the given numbers
24° = arcDC -22° . . . . . . . . . multiply by 2
46° = arcDC . . . . . . . . . . . . . add 22°
