$82.1$ $82.1$ and $7.9$ $7.9$ degrees.

Explanation:

Since sum of two complimentary angles is $90$ $90$ degrees, $\to$ $rarr$

$(7 x + 17) + (3 x - 20) = 90$ $(7x+17)+(3x-20)=90$
$:.10x-3=90$
$:.10x=93$
$:.x=9.3$

$:.(7 xx 9.3)+ 17 = 82.1$ degrees.
$:.(3 xx 9.3) -20 = 7.9$ degrees.

**Therefore, the two complimentary angles are $82.1$ and $7.9$ degrees. **

Check $rarr$
$82.1+7.9=90$ degrees.

Hope it Helps:)
