Ineed this question answered now with a mini explanation

100°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°

∠ECD = 40° ( vertical angle to ∠ACB )

Since CE ≅ ED then ΔCDE is isosceles and

∠CDE = ∠ECD = 40°

∠E = 180° - (40 + 40)° = 180° - 80° = 100°

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
