in ∆BES, A and R are the midpoints of BE and BS, respectively. What is SE if AR measures 15?​

Sagot :

Answer:

30

Step-by-step explanation:

The Midsegment Theorem states that the segment connecting the midpoints of two sides of a triangle is parallel to the third side and half as long.

AR = 1/2(SE)

15 = 1/2(SE)

SE = 30
