Complementary angles are two angles that add up to 90°

Supplementary angles are two angles that add up to 180°

Vertical angles are two angles that are opposite of each other and are also congruent

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.

Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of s

Allushta [10]

Answer:

The reasonable prediction for successful rolls is 4.

Step-by-step explanation:

Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as

$P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}$

$P(Success)=\dfrac{1}{6}$

The total success is given as

$P(Total\ Success)=P(Success)\times Number\ of\ events$

For 24 rolls it is given as

$P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4$

So the reasonable prediction for successful rolls is 4.
