Question

If = 63° and Z = 19 cm, what is the value of X to the nearest tenth of a centimeter?

A. 16.9 cm
B. 41.9 cm
C. 8.6 cm
D. 8 cm

Answer 1

picture below

Answer 2

which angle is 63° ?

Answer 3

acute, its at the top u see it in the picture?

Answer 4

ok use trigonometry :

x is adjacent to the angle of 63 degrees
and z is the hypotenuse of the right angled triangle

so cos 63 = adjacent / hypotenuse = x / 19
cos 63 = x / 19
x = 19 * cos 63

Answer 5

now its a calculator job to finish this off
if the diagram is roughly to scale it looks like x = either 8 or 8.6

Answer 6

ok thanks again!
