The angle complementary to angle 1 is angle 2
X=5
55+(5x+10)=90
(this is a right triangle since all three angles must add up to 180 degrees)
55+5x+10=90
65+5x=90
-65 -65
——————
5x=25
(get the x alone by dividing both sides by 5)
x=5
Answer:
20.78
Step-by-step explanation:
sin a = perpendicular/ hypotenuse
where a is the base angle
here a = 60
sin 60 = 18/ x
since,


√3 x = 36
x = 36/ √3
x = 36/ 1.732
x = 20.78
