Answer:

6.1°    and     83.9°

Step-by-step explanation:

Complementary angles sum 90°

a+b = 90°

a = b - 77.8

then:

(b - 77.8) + b = 90

2b - 77.8 = 90

2b = 90 + 77.8

2b = 167.8

b = 167.8/2

b = 83.9°

a = b - 77.8

a = 83.9 - 77.8

a = 6.1°

\text {Hello! Let's Solve this equation!}

\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}

\text {Here are some tips on dividing/multiplying equations like this.}

\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}

\text {Now Divide!}

\text {12/-4=}

\fbox {-3}

\text {As you can see 4 is a negative number so our result came out as a negative number.}

\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}
