Help ASAPS i need your help i give brainlist to the correct answer only the question 2 and 3

1. 9

2. 25

3. No (Explanation below)

Step-by-step explanation:

1. Original PT Formula is c=√a²+b²

BUT you're looking for the leg so you now have the formula of a=√c²-b² *c being the hypotenuse

a= √ 15² - 12²

a= √ 225 - 144

a= √81

a= 9

2. 16 + 9 = 25

* you're not looking for an angle therefore you are most likely looking for the length of the side. Simply add the AD and DC together to get the answer. If you were looking for an angle it'll be 180°.

3. NO because a right angle is an angle of exactly 90°, whether it be at a corner of a square/rectangle, a triangle, or where two perpendicular lines intersect. Angle ABC is an obtuse angle as it measures more than 90°

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
