4 0

Answer:

a_{10} = \frac{5}{8}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a_{1} r^{n-1}

Substitute in values

a_{10} = 320 × (\frac{1}{2}) ^{9}

                         = 320 × \frac{1}{512} = \frac{320}{512} = \frac{5}{8} = 0.625

Help help help please

Answer:

∠TUY = 120°

Step-by-step explanation:

There are two rules you can apply here:

1) The sum of the angles inside a triangle is 180°.  This means that ∠SUT = 180° - 70° - 50 ° = 60°

2) A vector coming out of a line two angles between itself and the line, and they add up to 180° as well. This means that ∠TUY = 180° - ∠SUT.  So ∠TUY = 180° - 60° = 120°

So the missing angle one hundred and twenty degrees.
