Answer:
<h2>-4x - 1</h2>
Step-by-step explanation:
Answer:b=39 degrees
Step-by-step explanation:
We know the whole angle is a 90 degree angle because of the right angle sign. So all we have to do is subtract 51 from 90, which is 39 degrees
1. 123-19=104
2. 104/4=26
The answer is 26 because 26x4=104+19=123
50 in the tens place, 8 in the ones
1. given
2. measure angle 1 plus measure angle 2 equals 90 degrees
3. B D bisects angle A D C
4. definition of angle bisector
5. definition of congruence
6. measure angle 1 is equal to measure angle 3
7. angle 1 is congruent to angle 3
7. definition of congruence
