Answer: <b is 59.3 degrees
Step-by-step explanation:
Triangles have total of 180 degrees
The bottom two points are both 4y
To solve: 4y+4y+(3y+14)=180
11y+14=180
-14
11y=166
Divide by 11
Y=15.1
So plug that in for y
3(15.1)+14=B
59.3

Answer:
k = ±4
Step-by-step explanation:
Equation of the circle is:
x² + y² = 5
This means from the general form of equation of a circle;
Centre coordinates is (0, 0) and radius is; √5.
The line 2x - y + k = 0 touches the circle. Thus, perpendicular distance from centre of the circle to this line is equal to the circle radius;
Thus;
|((2 - 0) - (1 × 0) + k)|/(√(2² + 1²)) = √5
|(1 + k)|/√5 = √5
Multiply both sides by √5 to get;
|1 + k| = 5
|k| = 5 - 1
k = ±4
