Q 7) Is this a valid argument? Given: If the sum of the measure of two angles equals 90° , then the angles are

complementary

The sum of the measures of /A and B is 90°

Conclusion:/ A and ZB are complementary,

1.Yes. This argument uses the Law of Detachment.

2.No. This is an improper use of the Law of Detachment.

3.Yes. This argument uses the Law of Syllogism.

4.No. This is an improper use of the Law of Syllogism.

step-by-step explanation:

answer: asdfghjkl,mnbv

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to
