In a right triangle, sin A equals cos B because A and B are complementary angles. Sin A cannot equal tan A, tan B, or cos A.
In a right triangle, the sine of an angle is defined as the length of the opposite side over the length of the hypotenuse. Therefore, sin A cannot be equivalent to tan A or tan B because tangent of an angle is the ratio of the opposite side to the adjacent side. The sine of angle A is not related to cos A because cosine of an angle is the length of the adjacent side over the length of the hypotenuse.
However, it's relevant to note that in a right triangle, the sine of an angle is equal to the cosine of its complementary angle. Since A and B are complementary angles in a right triangle (sum up to 90 degrees), it means that sin A equals cos B. So, the correct answer is C: cos B.

By the way those are two different problems
Answer:
24 square inches
Step-by-step explanation:
We are given Image of letter E with height of 12 and width of 7
Inside space of height of 5 and width of 6
Initially calculate the area of rectangle ABKL = length *width = 12*7= 84 square inches
Now to get the area of given figure subtract the area of rectangle CDFE and HGJI from the rectangle ABKL
Area of CDEF = Area of HGJI because the length and width of the rectangles is same
Thus Area of CDEF = length *width =5*6 = 30 square inches
Thus the Area of HGJI = 30 square inches
Now subtract the area of both rectangles from the area of rectangle ABKL
⇒84-(30+30)
= 24 square inches .
Hence the area of given figure LETTER E = 24 square inches .
