Step-by-step explanation:
m1=m2=m3=m5
m4=m6=m7
find m1,m2,m3 or m5
=180°- m4 or m6 or m7
find m4,m6 or m7
=180°- m1 or m2 or m3 or m5
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.

Answer:
The answer is 155.
Step-by-step explanation:
We can find the remaining parts of the triangle angles.
Answer:
Below.
Step-by-step explanation:
One method is by Trial and Improvement.
Example: Find the cube root of 20.
We know that cube root of 8 is 2 and cube root of 27 is 3 so the cube root of 20 is between 2 and 3.
So we could try 2.5:
2.5^3 = 6.25 * 2.5 - Use long multiplication to get 15.625.
So we need to go higher so we try 2.6*3:
= 17.576
2.7^3 = 19.683.
2.8^2 = 21.952.
The results are either side of 20 with 19.683 the closest.
So we can say that the cube root is 2.7 to the nearest tenth.
Further calculations are necessary to get an answer correct to the nearest hundredth.
This is a rather long process.......
