Step-by-step explanation:
Given
z = 119 + 120 i
Let
Squaring both sides
Comparing real and imaginary part
Re(LHS)=Re(RHS)
...........................(1)
comparing Im(LHS)=Im(RHS)
120=2pq
Substitute q in 1
Let
we take only Positive value because
x=149.85
thus
thus,
- HJ = 23.5 in
Take HJ = a, GH = b and GJ = c
- a = b + 2
- c = a + b - 17
- a + b + c = 73
put the value of a from equation 1 in equation 2
- c = (b + 2) + b − 17
- c = 2b − 15
now, put the value of a and c in equation 3
- b + 2 + b + 2b − 15 = 73
- 4b − 13 = 73
- 4b = 86
- b = 21.5 in
Now, we need to find HJ (a)
- a = b + 2
- a = 21.5 + 2
- a = 23.5 in
- HJ = 23.5 in
