Answer:
Step-by-step explanation:
Recursive formula
a1 = -17
a^n = a^n-1 + 5
Explicit formula:
a^n = -17 + (n-1) * 5
You need to find "two-fifths of 30." Of here means multiplication:
There are 12 athletes in the club.
Angle UTV is basically given: it's 138°.
Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have
So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°
