In ABC, Angle C Is A Right Angle. Which Statement Must Be True

Answers

Answer 1

Answer:

a

Step-by-step explanation:

a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13

this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13

hope this helps :)

Chris lost 4 of the 10 dollar bills that his parents gave him for his birthday. What percentage of his dollar bills did he lose?

Answers

Answer:

Step-by-step explanation:

Percentages are always out of 100 and can be illustrated by fractions.

[tex]\frac{4}{10}[/tex]   [tex]\frac{x}{100}[/tex]

To find out x, you multiply 100x4 then divide by 10.

This leaves us with [tex]\frac{40}{100}[/tex]

Which is also 40%.

Evaluate Sin^-1 sqrt2/2

Answers

Step-by-step explanation:

Let x = arcsin(√2/2).

We have sinx = √2/2, which is a basic trignometry identity. (sin45° = √2/2)

Since the range of arcsinx is [-90°, 90°] and 45° is within the range, the answer is 45° or π/4.
