This is a very poor quality question and the answer is wrong.
Since the larger triangle is a 3-4-5 type Pythagorean triangle with angle B = 90°, then the following HAS to be true:
angle A = 30°
angle C = 60°
vb1991Mate, not all right angle triangles have measure of angles : 30, 60 and 90.
All right angled triangle will follow Pythagoras Theorem. But for 30-60-90 type right triangle sides will be in ratio : 1 : \sqrt{3} : 2
Clearly, 3-4-5 do not follow above side ratio.
So, angles will not be in 30-60-90 form for 3-4-5 right triangle.
In fact for 3-4-5 right triangle corresponding angles are 36.87 - 53.13 - 90.
Hope this helps!!
