Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Sin 64=23/a. Let use trig identities to find other points
First, since sin and cos like are complementary angles we can use this formula

sin 64=23/a


So cos 26=sin 64 so B is a answer
Answer:
A
Step-by-step explanation:
Since D is an inscribed angle opposite of an 80 degree arc, its measure must be half that of the arc. Therefore, the measure of angle D is 80/2=40 degrees, or answer choice A. Hope this helps!
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x + 5 ← is in slope- intercept form
with slope m = - 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
