Answer: C) exactly one triangle
<u>Step-by-step explanation:</u>
Given: ∠A = 45°, ∠B = 65°, side c = 4 cm
By the Triangle Sum Theorem, ∠C = 70°
Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.

Thus, there is exactly one triangle.
3/12 + 10/12 = 13/12 because the points lie in-between the 1/6 and 2/6 marks and the 6/6 and 7/6 marks.
Answer:
x = 9
Step-by-step explanation:
The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:
7/4 = (x-3)+8/8
7/4 = (x+5)/8 cross multiply expressions
56 = 4x + 20 subtract 20 from both sides
36 = 4x divide both sides by 4
9 = x
Answer:
Step-by-step explanation:
Unless there is something special about this, the answer is 25 times the area of 1 parallogram.
Area of 1 parallelogram = Base * Height
Base = B = 5.3 cm
Height = H = 3.3 cm
Area = B*H
Area = 5.3 * 3.3
Area = 17.49
There are 25 pieces.
Total Area = 25 * 17.49
Total Area = 437.25 cm^2
