angle l is 90 degree
side kl is 10 cm
Step-by-step explanation:
given data
triangle klm
km =10 cm
angle k = 60 degree
angle m = 30 degree
to find out
angle l and the length of the side kl
solution
step (1) : first draw a line km of length 10 cm.
step (2) : at point k draw a ray kl making 60 degree to km.
step (3) : at point m draw a ray ml making 30 degree to mk.
now
we know sum of triangle is 180 degree
so
angle k + angle m + angle l = 180
angle l = 180 - (angle k + angle m )
angle l =180 - (60 + 30 )
angle l = 90 degree
and
we apply here sin formula
sin90 = ................1
1 =
x = 10
so side kl is 10 cm
