Answer:

53°

Explanation:

Complementary angle = 90°

So, 12° + (x+25°) = 90°

Subtract 12 from both sides

x+25°=78°

Subtract 25 from both sides

x=53°

Answer:

x=43

Explanation:

complementary angles will add up to equal 90 so we set up an equation to solve x

12+x+25=90

step 1 combine like terms

12+25=37 so now its

37+x=90

step 2 we subtract each side by 37

90-37=43

x=43

hope this helps and have a great day :)
