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 ^-^
Answer: 140
Step-by-step explanation:
Answer:
A.
and 
Step-by-step explanation:
Given:
Vertices of triangle RST are
and
.
Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.
Now, the co-ordinate rule for 90° rotation counter-clockwise is given as:
→ 
and
values interchange their places with
becoming negative when interchanged.
So,
→ 
→ 
→
⇒
→ 
Therefore, the image of the vertices are
and
.
Answer:
In math, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. You may use a slope while using coordinate planes.
