Hurry 30 points which triangles area would be calculated using the trigonometric area formula

PQR

Step-by-step explanation:

The trigonometric formula requires the length of two sides of the triangle and the included angle to determine the area

A = 1/2 ab sin C

PQR has 2 sides and the included angle

XYZ has 1 sides and the 2 angles

DEF has only 3 sides

ABC has 2 sides but not the included angle

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.
