Answer:
a. 157 cm
Step-by-step explanation:
Multiply the diameter times 3.14
3.14 x 50=157 cm.
answer: 157 cm
Answer:
Theorem : Opposite sides of a parallelogram are congruent or equal.
Let us suppose a parallelogram ABCD.
Given: and (According to the definition of parallelogram)
We have to prove that: AB is congruent to CD and BC is congruent to AD.
Prove: let us take two triangles, and
In these two triangles, { By the definition of alternative interior angles}
Similarly,
And, AC=AC (common segment)
By ASA,
thus By the property of congruent triangle, we can say that corresponding sides of are also congruent.
Thus, AB is congruent to CD and BC is congruent to AD.
Step-by-step explanation:
Answer:
csc(x)
Step-by-step explanation:
cos(x)cot(x)+sin(x)
We know that cot(x) = cos(x)/ sin (x)
cos(x)cos(x)/ sin(x)+sin(x)
cos^2 (x)/ sin + sin (x)
Getting a common denominator
cos^2 (x)/ sin + sin (x)* sin (x)/ sin(x)
(cos^2(x) + sin^2(x)) /sin(x)
We know that (cos^2(x) + sin^2(x)) = 1
1/sin (x)
1/ sin (x) =csc(x)
csc(x)
