Answer:
There are 5 theorem to prove the triangles are congruent. They are:
Answer:33 unit sq.
Step by step.
As we can see it is combination of three rectangles having two same small rectangkes so area of small rectangle is 2(2×3) is 12
Bow for bigger rectangle it is (7×3) is 21
so total area is 33 sq. unit
Answer:
6.7 cm
Step-by-step explanation:
To make use of the Law of Sines for finding b, you need to know the missing angle B. Since the sum of the angles of a triangle is 180°, you can find angle B as ...
B = 180° -82° -55° = 43°
Now, you put the numbers you know into the formula given and solve for b.
sin(A)/a = sin(B)/b
sin(55°)/(8 cm) = sin(43°)/b
Cross multiplying gives ...
b·sin(55°) = (8 cm)·sin(43°)
and dividing by the coefficient of b gives you ...
b = (8 cm)·sin(43°)/sin(55°) ≈ 6.7 cm
Step-by-step explaination
8 to the exponet 5
4.2 to the exponet 3
The answer is B because 1 is equivalent to 8/8
