Does anybody know how to determine the angle again? of q. b

Therefore the measur angle ACB

Step-by-step explanation:

Given:

ΔABC is a right Triangle at ∠A = 90°

AB = 15    ....Side Opposite to ∠ACB

AC = 8     ....Side Adjacent to ∠ACB

To Find:

m∠ACB = ?

Solution:

In Right Angle Triangle ABC, Tangent Identity we have

Substituting the values we get

Therefore the measur angle ACB

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
