Step-by-step explanation:
p = -1, -4
q = -2, 2
p-q = (-1, -4) -1(-2, 2)
= 1, -6
Answer:
Step-by-step explanation:
In
O, ST and VT are tangents at points S and V respectively.
In quadrilateral OSTV,
(By interior angle sum postulate of a quadrilateral)
(Measure of minor arc is equal to measure of its corresponding central angle)
(By arc sum property of a circle)

So 3 times the measure of a small angle
3x + x= 180
4x = 180
X= 45
3(45) + 4(45) = 180
Hope this helps!
