Let one angle be x
Let another angle be 17x
17x+x = 90
18x = 90
x = 90/18 = 5
one angle = x = 5
another angle = 17x =17*5 = 85
I hope it is helpful:D

Answer:

Since the parametric equation is given as

$x(t)=4cos(\pt t),y(t)=4sin(\pi t)\\\\\therefore x(t)^{2}+y(t)^{2}=16cos^{2}(\pi t)+16sin^{2}(\pi t)\\\\x(t)^{2}+y(t)^{2}=16\\\\$

$\therefore \frac{x^{2}}{4^{2}}+\frac{y^{2}}{4^{2}}=1\\\\comparingwith\\\\\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1\\\\\therefore a=4,b=4$

Check the picture below.

btw, when Pythagoras said the square of this equals that and so on, he really meant the square or square area.
