Answer=C
The conversion formula between Celsius and Fahrenheit is:
°F=(9/5*°C)+32
Based on the information given, we know that °C=30. So we can solve for °F.
°F=(9/5*°C)+32
°F=(9/5*30)+32
°F=(54)+32
°F=86
30 Degrees Celcius is equivalent to 86 degrees Fahrenheit.

Answer: i think it’s A and D
Answer:
DE = 20units
Step-by-step explanation:
In Δ ABC,
angle A is congruent to angle B.... (given)
therefore, ΔABC is an isoceles triangle.
therefore, CA = CB..... (side opposite to congruent angles are congruent in an isoceles triangle)
therefore, CB = 4 units
In ΔCDE,
angle D is congruent to angle E.... (given)
therefore, ΔCDE is an isoceles triangle.
therefore, CD = CE
therefore, CD = 8 units
ΔCDE ~ ΔCBA
therefore,
