Answer:
Option C
Step-by-step explanation:
ΔABC and ΔDEF are similar triangles.
By the property of similar triangles, corresponding sides of the similar triangle are proportional.



DE = 3
Perimeter of ΔDEF = Sum of measures of the sides of the triangle
= DE + EF + DF
= 3 + 3 + 5
= 11
Therefore, Option C will be the correct option.
Answer:
∠4 = 97°
Step-by-step explanation:
If ∠4 and ∠5 are supplementary, it means they add up to 180°. So,
m∠4 + m∠5 = 180°
m∠4 + 83° = 180°
m∠4 = 180° - 83°
∠4 = 97°
hope this helps!! p.s. i really need brainliest :)
