Question

Find the value of x. round to the nearest tenth

Answer 1

*79.40*

Explanation:

using sine rule..

a/sinA = b/sinB

42/sin19= x/sin142

x= sin142*42/sin19

= 79.42356..

to the nearest tenth = 79.40.

Answer 2

Explanation:

a/sinA = b/sinB

(42/sin19) = (x/sin142)

x = (sin142 *42 / sin19)

Round to the nearest tenth -> 79.4
