For the right triangles below, find the values of the lengths a and c. Round your answers to the nearest tenths

a=7.1

b = 4.6

Step-by-step explanation:

For the first triangle,

taking 45 as reference angle,

cos45 = b/h

or, cos45 = 5/a

or, a = 5/cos45

so, a = 7.07

so, a = 7.1

Again,

taking 60 as reference angle,

tan60 = p/b

or, tan60 = 8/c

or, c = 8/tan60

so, c = 4.6

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
