Answer:
71°
Step-by-step explanation:
The triangle shown is an isosceles triangle. Isosceles triangles have two equal sides and two equal angles. When all 3 angles are added, it should have a sum of 180°. The tip of the triangle is the part of the triangle with the smallest degree/angle. So the two remaining angles are the same amount.
180°=38°+x+?
180°=38°+71°+71°
Both missing angles are the same degree, and when both are added to 38, it has a sum of 180. x is equal to 71°.
Range = y
domain = x
just substitute in the numbers for x to get your y
X=-.5, it’s less than 0, and concave up & increasing in this situation are the same.
The chance is 1 out of 3. The fraction is ⅓ or 1 over three.
It is tiring to type this again but... hope this helps.
