First we write the statement step by step to find the correct equation.
We have then:
x - y
subtracted from 0
(0) - (x-y)
Resolving:
(0) - (x-y) = - x + y
You should notice that different signs are subtracted and equal signs are added.
Answer:
A) -x + y
I'm assuming that the full statement is ΔABC is congruent to ΔDEF.
Given:
m∠A = 70
m∠B = 47
m∠C = 63
Since both triangles are congruent, the corresponding angles in ΔDEF also has the same measure as those in ΔABC.
m∠D = 70
m∠E = 47
m∠F = 63
The measure of angle F is 63.
12 - 3 = 9
3 + 9 = 12
12 - 9 = 3
10:12 pm
6 hours before is 9pm
3/4=45/60
add 45+37=72-60=12=1+9=10:12
