Answer: 48°
Step-by-step explanation: AD=AB, ∠ADC=∠ABC.
(5x-147)°=2x°, 3x=147, x=49.
So, ∠ADC=∠ABC=98°,
∠DCB=360°-{116°+2(98°)}
=360°-(116°+196°)
=360°-312°
=48°
Answer:
23
Step-by-step explanation:
100 is the exterior angle.
( 2x + 3 ) and 51 are interior angles.
Formula : -
Exterior angles = Sum of two interior angles.
100 = 2x + 3 + 51
100 = 2x + 54
2x = 100 - 54
2x = 46
x = 46 / 2
x = 23

Answer: The correct answer is Choice C.
Step-by-step explanation: The drama club raised 150% of their goal, which is represented by choice c.
The proper way to calculate this percentage is to calculate how much they earned over the goal. They earned $150 over a goal of $300, so you divide 150 by 300 to determine the percentage.
150/300 = .5, or 50%
So, they earned 100% (300) plus 50% (150), for a total of 150% of the goal.
The correct answer is D. D'(1, 5), E'(-1, 3), F'(-1, -4), G'(1, -2).
It's because of this: You need to calculate the distances, and they are in this case symmetric, so you look how far is from one side, and it will be the same on the other side. When you put it on graph, the coordinates are clear and the correct answer is D.
