Answer:
x =
- a
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2T = n(a + x)d
Since n and d are both multipliers, divide both sides by nd
= a + x
Isolate x by subtracting a from both sides, hence
x =
- a
Answer:
They are similar using the angle-angle property.
Step-by-step explanation:
Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.
