Alternate interior= 2 and 6
Consecutive int.= 7 and 6
Corresponding = 1 and 3
Alternate ext.= 1 and 5
Vertical= 1 and 7
#41 = measuere 6 and 11 add up to 180, subtract 180 from 50 and you get 130
Step-by-step explanation:
Draw the triangle formed by the ray.
The hypotenuse of the triangle is:
c² = a² + b²
c² = (-5)² + (2√7)²
c² = 25 + 28
c = √53
Therefore:
cos β = -5 / √53
Or, as a proper fraction:
cos β = -5√53 / 53
Answer:
Two distinct roots means two real solutions for x (the parabola needs to cross the x-axis twice)

Answer:
angles A and B = 65° angles C and D= 115
Step-by-step explanation:
angle A = angle B so
180-50=130
130/2=65
then 180-65=115
