Which statement is false?

Sidana [21]

Trigonometric functions which are related by having the same value at complementary angles are called cofunctions. Cofunctions of complementary angles are equal.

A. csc 20' = csc(90-70)=sec 70

B. cos 87' = cos (90-3)=sin 3'

C. csc 40' = csc(90-50) =sec50'

D. tan 15' = tan(90-75)= cot 75'

Among all the option c is not correct.

Option C is false.

3. The volume V of a cone is given by the

hammer [34]

Answer:

Step-by-step explanation:

The most appropriate choice of volume of a cone is given by-

$h=\frac{3v}{\pi r^{2} }$

What is volume of a cone?

The volume of a cone is the amount of space occupied by the cone.

Volume of a cone is given by the formula

$V=\frac{1}{3} \pi r^{2} h$

Where, r is the radius of cone and h is the height of the cone.

Here,

$V=\frac{1}{3} \pi r^{2} h\\3V=\pi r^2h\\h=\frac{3V}{\pi r^2}$

5+2x=2x+6 What's the answer?

Marina86 [1]

Answer:

Below!

Step-by-step explanation:

We can solve this with the help of equations.

5 + 2x = 2x + 6
=> -2x + 2x = -5 + 6
=> 0 ≠ 1

Since we are getting 0 ≠ 1 as our result, the problem has no solution.

Hoped this helped.
