For number 1 and 2 you are correct but I'm not sure for number 3
Firstly you can do 8 x 41 = 328.
Then 6 x 19 = 114,
114 + 328 = 442^2.
Hope this helps.

Answer:
36°, 63°, 81°
Step-by-step explanation:
Let 4x = measure of angle 1
7x = measure of angle 2
9x = measure of angle 3
The sum of the measures of the angles of a triangle = 180
So 4x + 7x + 9x = 180
20x = 180
x = 9
4x = 36 = measure of angle 1
7x = 63 = measure of angle 2
9x = 81 = measure of angle 3
Check: 36 + 63 + 81 = 180
