Answer:
Triangle PST ≅ Triangle PQR by ASA
Step-by-step explanation:
We know that because line segments PS and PR are congruent, then ∠PRS and ∠PSR must also be congruent because of the Isosceles Triangle Theorem, which states that if two sides of a triangle are congruent, then angles opposite those sides are congruent.
Therefore, the angles supplementary to ∠PRS and ∠PSR (∠PRQ and ∠PST respectively) must also be congruent to each other since we've already stated that ∠PRS and ∠PSR are congruent due to the Isosceles Triangle Theorem.
So, we can prove triangles PST and PQR congruent by ASA (Angle-Side-Angle).
Pretty sure u can not simplify that further since there are no like terms? could be wrong
14 I think it may be wrong sorry if it is...I just divided
Answer:
54
Step-by-step explanation:
First add 7 to both sides to cancel out the -7
y/6-7(+7)=2(+7)
Then, multiply 6 to both sides to cancel the 6
y/6(6)=9(6)
y=54
Part 3 of the graph shows a linear relationship. This is because a line that is linear is a straight line and part 3 of the graph is the only straight line. Hope this helps!
