Given the statement, LEI=BNZ and the diagrams shown, determine the value of x.

WARRIOR [948]

Answer:

x = 20

Step-by-step explanation:

Given the triangles are congruent then corresponding angles are congruent, so

∠ N = ∠ E

To calculate ∠ E subtract the sum of the 2 given angles from 180

∠ E = 180 - (x - 5 + 4x - 10)

= 180 - (5x - 15)

Equate ∠ N and ∠ E

5x - 5 = 180 - 5x + 15 ( add 5x to both sides )

10x - 5 = 195 ( add 5 to both sides )

10x = 200 ( divide both sides by 10 )

x = 20

Wayne traveled 90 miles total.
60 miles was 2/3 of the distance.
30 miles is 1/3.
90 miles divided by 4 hours.
90/4
22.5 or 22 1/2 mph
