Answer:
x = 9
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
50° is an exterior angle of the triangle, thus
38 + 4x - 24 = 50 , that is
14 + 4x = 50 ( subtract 14 from both sides )
4x = 36 ( divide both sides by 4 )
x = 9
We divide both sides by 160. Therefore, the boat will travel about 0.53 miles in 1 minute.
63 I think, you would subtract
Answer:
Step-by-step explanation:
f(x)=x+1
then,
f(-5)=(-5)+1
=-4
