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

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
