Answer:
Answer is C.
Step-by-step explanation:
Answer:
699(0.90)(1.07)
Step-by-step explanation:
Given that:
Regular cost of couch = $699
Onsale percentage = 10%
Sales tax in purchase = 7%
Final price of couch :
New price at Selling percentage :
Regular price * (discount) * (sales tax percentage)
Regular price * (100% - 10%) * (100 + 7%)
699 * (1 - 0.1) * (1 + 0.07)
699 * 0.90 * 1.07
699(0.90)(1.07)
ANSWER
The correct answer is 19.1
EXPLANATION
The perimeter of triangle OQR is the sum of the distance around the triangle.
Thus,

We can observe that two of the angles are equal.
The angles that are equal measures 62° each.
Therefore triangle OQR is an isosceles triangle. This means that

Hence,

units.
To find this answer you will use the formula for finding the area of the triangle because that shape is a triangle.
A = 1/2 bh
198 = 1/2 x b x 12
198 = 6b
b = 33 cm
We know the total area and we know the slant height is 12 cm so we substitute these in and solve for h.
The length of the base edge is 33 cm. You should substitute this back in to check.
1/2 x 33 x 12 = 198 square cm.
