Answer:
looking at the equation one plus one we see there can be many answers for example we can take one plus ine and change it to a number of different questions including but not limited to 1+1 1-1 1/1 1x1 1^1 etc looking at other results we can then determine tat 1+1=2 all though alternative answers could be present
Step-by-step explanation:
Δ YX Z And Δ VUW are SIMILAR because all their respective angles are congruent:
∠ y = 90°; ∠ v = 90°
∠ x = 67°; ∠ u = 67°
∠ z = 23°; ∠ w = 23°
Two triangles are similar if their related angles are congruent (answer B)
If i’m not wrong i think it might be b
