Sketch and solve the following triangles. 1. The legs of a right triangle measure 5cm and 12cm. What is the measure of its hypotenuse?

2. In ∆ABC and C is a right angle, if c = 12 and b = 10, find cos A.

3. In ∆ABC and C is a right angle, the opposite of ∠A = 12. if the hypotenuse = 13, find tan θ.

4. If sin A = What is tan A?

5. If cot θ = What is sec θ?


​

answer of 1 is 13

Step-by-step explanation:

well there are two sides given 12cm and 5cm respectively so you can use the formula

H2=P2+B2 ... 2meanssquare

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
