3 lines are shown. A line with points C, A, F intersects a line with points E, A, B at point A. A line extends from point A to p
Verizon [17]

Answer:

m < EAD = 29 degrees

m < CAB = 119 degrees

Given :

The question states that m < CAE = m<FAB = 61 degrees and m<DAF = 90 degrees

Solution:

1. Since line CAF and EAB intersect each other, m<CAF = m< EAF - (opposite vertical angles are equivalent)

2. m<BAC + m<EAC = 180 degrees (sum of linear pair)

3. m<CAB = 180 degrees - m<EAC

4. Equation 1: m<CAB = m<EAF = 119 degrees

5. m<EAF = m<EAD + m< DAF

6. m<EAD = m<EAF - m<DAF

7. m<EAD = 119 degrees-90 degrees = 29 degrees

Hope this helps!!! :)

How would 5/9 be classified? 1. Rational and real? 2. Whole and integer? 3. Only real? Or 4. Only irrational
Elena-2011 [213]
A rational number is any number that can be written as a ratio or a fraction.

So 5/9 is  a rational number. So basically that eliminates 2, 3, and 4.

And we are left with 1. as our answer choice which is Rational and real.
