Given the geometric sequence: 7, 21, 63, 189... A. Find an explicit formula for the sequence.
B. Use the formula to find 011-
O an = 7(3)" ; 1,240,029
O an - 7(3)n-1; 413,343
O an = 3n +4; 37
an = 7 + 3n; 38

no one knows lol

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
