Tan205° = .466 tan55° = 1.428 tan25° = .466 -tan25° = " so just tan25
Answer:
Step-by-step explanation:
The average value theorem sets:
if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that
, where
f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4
f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4


⇒

c≅130
We are given with
arc AC = 130
The measure of the arc on the other side of the circle is
360 - 130 = 230
Therefore, according to the theorem on circles, the measure of angle ABC is
(1/2) ( 230 - 130) = 50
Answer:
Angle 5, 4, and 7.
Step-by-step explanation:
Angle 2 is vertical to angle 5, making them congruent.
Angle 2 corresponds with angle 4, making them congruent.
Angle 2 is an alternate interior to angle 7, making them congruent.
]
The rest of the angles just combine with angle two to make 180.
