First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.
m∠O = 2 (65°) = 130°
Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.
m∠O + m∠C + m∠B + m∠A = 360°
Substituting the known values,
130° + 90° + 90° + m∠A = 360°
The value of m∠A is equal to 50°.
<em>Answer: 50°</em>
The airplane is ascending from it previous destination and then descending to its next destination, making its speed decline and remain the same.
Answer:
d<63/5
Step-by-step explanation:
15>5/3d-6
5/3d-6<15
5/3d<15+6
5/3d<21
d<21/(5/3)
d<(21/1)(3/5)
d<63/5
Answer:
Step-by-step explanation:
There must be an error in the question.
Equation for circle of radius r, centered at (h,k):
(x-h)² + (y-k)² = r²
apply your data
(x-2)² + (y+5)² = 4²
which doesn't fit any of the answer choices. Did you mean the center to be (2,-3)?
