Find the value of x.
please i need the answer today.
Thank you.

x = 61.92751306

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta =  opposite / adjacent

tan x = 15/8

Take the inverse tan on each side

tan ^ -1 (tan x) = tan ^ -1 (15/8)

x = 61.92751306

Step-by-step explanation:

tan x = 15/8

tanx = 15/8    ... 1

cot x = 8/15 2

multiply 1 and 2

tanx * cotx = 15/8 * 8/15

x [ tan * 1/tan]  =  1

x = 1

hope it is correct. i just tried

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
