Question

Find the value of x and y:

Answer 1

Answer:

x = 5

y = 40°

Step-by-step explanation:

the median and the base of the large triangle are parallel so angle y has the same measure as the one labeled as 40°

the median is half the base of the large triangle, so 5x = 8x + 10/2

cross-multiply:  10x = 8x + 10

2x = 10

x = 5
