Answer:
34
Step-by-step explanation:
2b + 7z when b = 3, z = 4
2*3 = 6
7*4 = 28
28 + 6 = 34
Hope this helps!
To prove it, you can use the Pythagorean theorem and plug in the numbers. If it equals the same number on both sides it is a Pythagorean triple.
a² + b² = c² (c is the hypotenuse or the longest side/length)
77² + 420² = 427²
5929 + 176400 = 182329
182329 = 182329
It is a Pythagorean triple
Answer:
z = 3/2 (turn it into decimal if required)
Step-by-step explanation:
Let the angle be x.
Taking x as reference angle
cosx = b/h
or, cosx= z/3
Again taking x as reference angle for the bigger triangle,
cosx = b/h
or, cosx = 3/6
or, cosx = 1/2
so, x = 60
Now,
As we found out,
cosx = z/3
or, cos60 = z/3
or, 1/2 = z/3
or, 3 =2z
so, z = 3/2
777 divided by 21 = 34 with a remainder of 3
