The measure of one angle of a triangle is 105°. What do you know about the measures of the other two angles? Check all that appl
y. Both angles are acute. The sum of the measures of the two angles is 75°. The sum of the measures of the two angles is 155°. One of the angles is a right angle. The measure of neither angle is more than 75°. The measures of the other angles must be 105° too. The measure of one of the other angles equals 75°. The measure of one of the other angles must be 45°.
We subtract 26 1/6 from 68 1/2. We do this by finding the LCM of 6 and 2. That is 6. We multiply 1/2 by 3/3 to get 3/6. Now, we subtract. 68 - 26 is 42, and 3/6 - 1/6 is 2/6. Our answer is 42 2/6. That can be simplified to 42 1/3.
