Answer:

∠3 = 140°

Step-by-step explanation:

∠4 = 40°

∠4 = ∠1 <u><em>(vertical angles)</em></u>

∠1 = ∠2 <u><em>(alternate angles)</em></u>

∠2 = 40°

So,

∠2+∠3 = 180 <em><u>[Angles on a straight line add up to 180°]</u></em>

40 + ∠3 = 180

∠3 = 180-40

∠3 = 140°

Answer:

Angle 3 = 140°

Step-by-step explanation:

Angle 4 is equal to 40° and on a flat surface of 180°, that is, the first horizontal line, angle A is equal to 140° because 180° - 40° = 140°. Angle A is congruent to angle 3, therefore, angle 3 is also 140°.

The 13th term of this geometric sequence is 16,384 and the first term is 4. what is the common ratio
valina [46]
A geometric sequence is a sequence with a common ratio multiplied by previous term to give the next. Lets call x the common ratio, so we know that 4 was multiplied by x to give the second term, and so forth until it was multiplied again and again by x until the 16384 was reached which happens to be the 13th term, that means that 4x was multiplied by x 12 more times to give 16384, that is:
4x^12 = 16384
x^12 = 4096
x = 4096^-12
x = 4.48 x 10^-44
that is the common ratio
