Step-by-step explanation:
Sum of interior angles of a polygon is given by (n-2)180°
where,n is the number of sides.
Since this polygon has 5sides,
sum of the interior angles = (5-2)180°=540°
x+150°+120°+75°+60°=540°
x°=540°-405° = 135°
Answer:
1
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° =
, then
sin60° =
=
=
( cross- multiply )
x
= 28
( divide both sides by
)
x = 28
-----------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° =
, then
tan60° =
=
=
( multiply both sides by y )
14
= y
( divide both sides by
)
y = 14
