Being able to write fractions in simplest form can make operations much easier. Also, to compare fractions, some may have to be in the simplest form.
Answer: The correct option is (a), i.e., cos B= sin A.
Explanation:
It is given that the ∠B = ∠C and ∠D is a right angle.
Since two corresponding angles of both triangles are same, so by angel sum property three angles are also equal. Therefore by AAA rule both triangles are similar.
It is given that,


Using angle sum property angle C is written as,



By using quadrant concepts.

Therefore option A is correct.
Answer:
answer 100%100 is 146215771
Answer:
The answer would me; M.
Step-by-step explanation:
Look at were all the lines meet.
(0,2)((-2,-4)
slope = (2+4)/(0+2) = 6/2 = 3
equation
y - 5 = 3(x - 1)
