joanne cannot decide which of two washing machines to buy. The selling price of each is $660. The first is marked down by 40%.
The second is marked down by 30% with an additional 10% off. Find the sale price of each washing machine. Use pencil and paper. Explain why joanne should buy the first washing machine rather than the second if the machines are the same except for the selling price.
From the figure, you can say that angle E is equal to angle C because they both are vertically opposite. So, you can find angle D by substracting angle E and D from 360° (sum of angles at a point) and dividing the answer by two: 360°-54°-54° = 252° 252°÷2 = 126° Then, you can find angle H by substracting the values of angle G and angle D from 180° (sum of angles in a triangle): 180°-126°-29° = 25° Therefore, the answer is 25°. I hope this answered your question :)
