Answer:
A and C
Step-by-step explanation:
- A right triangle consists of two legs and a hypotenuse.
- To find hypotenuse, we use The Pythagorean Theorem
- The Pythagorean Theorem =

- two legs meet at a 90° angle and the hypotenuse is the longest side
3 - 4 - 5
6 - 8 - 10
7 - 24 - 25
5 - 12 - 13
are some basic right triangle
(about more, look picture)
<em><u>Just use hypotenuse formula :</u></em>
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
Option C is correct

Option A is correct

But B isn't correct
Hope this helps ^-^
for this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle. So:

Answer:

N would equal 57 × 3 which is 171.
Answer:
4th Option
Step-by-step explanation:
-3xy + 2wx
M<YZW = 63 because in an isosceles triangle, the base angles are congruent. (<X and <YZW are both base angles)
