In the given diagram, line BG bisects ∠ABC and ∠DEF, m∠ABC= 112°, and ∠ABC≅∠DEF. So the measure of angles are :
1. m∠DEF= 112° because ∠ABC≅∠DEF
2. m∠ABG= 56° because a straight line BG is bisecting ∠ABC in two equal parts. So,
3. m∠CBG= 56° because ∠ABG and ∠CBG are equal.
4. m∠DEG= 56° because ∠ABG ≅ ∠DEG
Answer:
The correct ordered pair is (7,1)
Step-by-step explanation:
The given system has equations:
We make x the subject in the first equation to get:
Put equation 3 into equation 2 to get:
Expand:
Put y=1 into equation 3 and solve for x.
The correct ordered pair is (7,1)
