In the diagram, |QR| = 10m, |SR| = 8m
< QPS = 30...
< QPS = 30...
In the diagram, |QR| = 10m, |SR| = 8m
< QPS = 30o, < QRP = 90o and |PS| = x, Find x
A.
1.32m
B.
6.32m
C.
9.32m
D.
17.32
Correct answer is C
In right angled △QPR
tan 30o = 10x+8
(x + 8) tan 30 = 10
x + 8 = 100.5773
x +8 = 17.3
x = 17.3 - 8
x = 9.32
