+(25)(2)−15−3
=6+(25)(2)−15−3
=6+50−15−3
=56−15−3
=41−3
=38
Answer:
70°
Step-by-step explanation:
The tangent- chord angle is one half the measure of the intercepted arc.
intercepted arc = 360° - 220° = 140°, thus
inscribed angle = 0.5 × 140° = 70°
The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3
Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)
Answer:
Step-by-step explanation:
Distance between two points and is given by the formula,
Distance =
a). A(-6, -4), B(-3, -1)
Distance between A and B =
=
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D =
=
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance =
=
= 10√2
= 14.14
≈ 14.1 units
