Hey there!

$\bold{x^2-10+25=35}$ Firstly, we have to to simplify both sides of your equation $\bold{x^2-10+25=35}$ $\bold{-10+25=15}$ Firstly, now that we got that portion out the way, let's $\bold{subtract}$ by the number $\bold{15}$ on each of your sides $\bold{x^2+15-15=35-15}$ $\bold{Cancel:15-15}$ $\bold{Keep:35-15}$ $\bold{35-15=20}$ We get: $\bold{x^2=20}$ Take the square root of the number $\bold{x=}$ ± $\bold{\sqrt{20}}$ $\boxed{\boxed{\bold{x=2\sqrt{5}[or]x=-2\sqrt{5}}}}$ $\checkmark$ Good luck on your assignment and enjoy your day!~ $\frak{LoveYourselfFirst:)}$

The fourth choice

24.2° and 114.2°

Step-by-step explanation:

Complementary angles add up to 90°

Supplementary angles add up to 180°

*a trick to remember this is to know that C is before S in the alphabet, and 90 is before 180, so Complementary is 90 and Supplementary is 180

Step 1: Find the complementary angle

Take 90° and subtract the give angle to find the angle you would need...

90° - 65.8° = 24.2°

Step 1: Find the supplementary angle

Take 180° and subtract the give angle to find the angle you would need...

180° - 65.8° = 114.2°
