Answer:
x = 10; WX = 5; HJ = 10
Step-by-step explanation:
The hash marks indicate that points W and X are midpoints of their respective segments. That makes WX a midline of the triangle. The midline is always half the length of the base (HJ). We can use this fact to write an equation relating the lengths.
HJ = 2·WX
x = 2(x -5) . . . .substitute the given expressions
x = 2x -10 . . . . eliminate parentheses
10 = x . . . . . . . add 10-x to both sides
This value of x tells you that ...
HJ = x = 10
WX = x -5 = 5

Step-by-step explanation:
Answer:
- 18. x = 24.5
- 19. x = 4
- 21. x = 10
Step-by-step explanation:
Corresponding sides have same ratio
Q18
- 7/6 = x / (27- 6)
- 6x = 7*21
- x = 147/6
- x = 24.5
Q19
- (x + 5)/15 = (5x + 1)/35
- (x + 5)/3 = (5x + 1)/7
- 7(x + 5) = 3(5x + 1)
- 7x + 35 = 15x + 3
- 15x - 7x = 35 - 3
- 8x = 32
- x = 4
Q21
- (x + 6)/24 = (2x - 2)/27
- (x + 6)/8 = (2x - 2)/9
- 8(2x - 2) = 9(x + 6)
- 16x - 16 = 9x + 54
- 16x - 9x = 54 + 16
- 7x = 70
- x = 10
