3×-1= -3 if u put it the other way it would will still be -3
3/8 + 2/8 = 5/8
8/8 - 1/8 = 7/8
7/8 - 5/8 = 2/8 = 1/4
he used 1/4 to paint the bird house.
Answer:
33.53
Step-by-step explanation:
OB is a radius of the circle, and OC is also a radius of the circle, so both are equal length. That makes ΔOBC an isosceles triangle.
If we cut ΔOBC in half, the angle formed is 125° / 2 = 62.5°.
Therefore:
sin 62.5 = (x/2) / 18.9
x = 37.8 sin 62.5
x ≈ 33.53
