Molodets [167]

Answer:

an = -4 * (-3)^ (n-1)

513560652

Step-by-step explanation:

We can find the common ratio

12/-4 = -3

r =-3

The explicit formula is

an =a1 r^(n-1)

an = -4 * (-3)^ (n-1)

We want the 18 th term

a 18 = -4 (-3) ^ 17

If M∠ ABD =64 and M∠CBD=30 then M∠ABC= <br> Need help

Leno4ka [110]

Answer:

$\displaystyle m\angle ABC = 34^\circ$

Step-by-step explanation:

∠ABD is the sum of the angles ∠ABC and ∠CBD. In other words:

$\displaystyle m\angle ABD = m\angle ABC + m\angle CBD$

Substitute in known values:

$\displaystyle \left(64^\circ\right) = m\angle ABC + \left(30^\circ\right)$

And subtract. Hence:

$\displaystyle m\angle ABC = 34^\circ$

In conclusion, ∠ABC measures 34°.
