Answer:
∠a = <u>51°</u>
∠b = <u>48°</u>
∠c = <u>70°</u>
Step-by-step explanation:
∠c = 180° - 110° = <u>70°</u> (Angles on a straight line add up to 180°)
∠ADB = 180° - (110° + 19°) = <u>51°</u> (Angles on a triangle add up to 180°)
∴ ∠a = <u>51°</u> (Alternate angles are equal)
∠A = 180° - (51° + 62°) = <u>67°</u> (Angles on a triangle add up to 180°)
∠CAB = 67° - 19° = <u>48°</u>
∴ ∠b = <u>48°</u> (Alternate angles are equal)
I believe C is the correct answer.
Because y should be graphed as positive, or to the right, ruling out option B. In option A the dashed line representing the second inequality is incorrect, so C is your answer.
The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies
The copy machine makes 105 copies per minutes.

The answer is an octagon.
The area of a triangle is (base*height)/2
Therefore: 12*10=120/2=60. Since there are three triangles then you multiply 60 by three. 60*3=180
Since the triangle in the middle is equilateral the height is 10. (10*10)/2=50
180+50=230
The answer is 230 inches²
