In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

B

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for x

∠A = 180° - (90 + 40)° = 180° - 130° = 50°

tan50° = =

multiply both sides by 8

x = 8tan50° → B

step-by-step explanation:

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.
