Answer:
The sides of triangle are 20,21,29.
The given triangle is right angles triangle with 29 as hypotenuse.
Let the length of altitudes be a,b,c
We can say that a=20,b=21, since it is right angled triangle and c is the length of altitude to the hypotenuse
By equating area, we get 21×20×21=21×29×c
⇒c=29420
Therefore the lengths of altitudes will be a+b+c=20+21+29420=291609
So the correct option is A.

Answer:
90°
Step-by-step explanation:
as 20,21,29 are pythagorean triplet the triangle is a right angled triangle so the hypotenuse will be the longest side(basic property of right angle triangle) which is opposite of the right angle
so the answer is 90°
