If two angles of a triangle are complementary find the number of degrees in the third angle of the triangle

The measure of the third angle is a 90 degrees

Step-by-step explanation:

Let

A and B ----> two complementary angles in a triangle

C ---> the measure of the third angle in a triangle

we know that

If two angles are complementary, then their sum is equal to 90 degrees

so

---> equation A

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

----> equation B

substitute equation A in equation B

solve for C

subtract 90 degrees both sides

therefore

we have a right triangle

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
