Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.
<h3>How to verify if a triangle form Pythagorean triple?</h3>
Pythagoras's principle follows the rule:
c² = a² + b²
where
- a and b are the legs
- c is the hypotenuse side.
Therefore, Pythagorean triples are a² + b² = c² where a, b and c are the three positive integers. The most known and smallest triplets are (3,4,5).
If we reduced the length of the side of the triangle with the greatest common factor, it should give us 3, 4, 5.
Hence,
21, 28 and 35 has greatest common factor as 7
21 / 7 , 28 / 7 and 35 / 7
3, 4, 5
Hence, multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

it looks like its answers two, four, and five.
tell me how you did !
Answer:
Option (3)
Step-by-step explanation:
If a point having coordinates of a point (x, y),
If this point is rotated by an angle of 90 degrees clockwise about the origin then the coordinates of the image will follow the rule,
(x, y) → (y, -x)
If a point A is (3, -9) and this point is following the the same rule, new image point will be,
A(3, -9) → A'(-9, -3)
Option (3) will be the correct option.
