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:
x = a + 7
y = b-a
To prove
x + y = b + 7.
- x+y= (a+7) + (b-a)
=a+7+b-a
=a-a+7+b
=0 + 7+b
= b+7
Proved ✅
The value of a is 90 degrres
