Answer:
Step-by-step explanation: bro use sin=opposite/hypotenuse
Apply the standard equation of a circle:
(x-h)²+(y-k)²=R²
== (x-3)²+(y+2)²=25
W = words per minute = 80
t = time in minutes = 30
The total number of words per 30 minutes is w*t = 80*30 = 2400 words
Answer:
Angle DCA = Angle CAB. (Alternate Interior Angle)
Angle DCA = 68°
Angles(DCA + ACB + BCE) = 180°. (Linear Pair)
Angle ACB + 68° + 33° = 180°
Angle ACB = 79°
Therefore,
Angle ABC = 33°. (Alternate Interior Angle)
