In δabc, bc = 12.35, ac = 8.75 centimeters, and m = 37°. what are m and m to two decimal places?
1)m∠a ≈ 25.24°, m∠c ≈ 117.76°

2)m∠a ≈ 58.15°, m∠c ≈ 84.85°

3)m∠a ≈ 25.24°, m∠c ≈ 64.76°

4)m∠a ≈ 58.15°, m∠c ≈ 31.85°

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
