Answer:
There are 21 ways to choose the first person, 20 ways to choose the second, 19 ways for the third and 18 ways for the fourth so the answer is 21 * 20 * 19 * 18 = 143640.
Honestly I don’t know but I think it’s d
7900 should be the answer, is there any options?
Answer:
They are not similar,
the reason why is because 56 degrees is given and the two sides that form the angle are the same length whilst the other triangle has two uneven sides that form a 56 degree angle.
The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
GX/BX = UH/NH
GX = BX·UH/NH
GX = 7·18/(3√11)
GX = (42/11)√11
GB/BX = UN/NH
GB = BX·UN/NH
GB = 7·15/(3√11)
GB = (35/11)√11
