Answer:
The length of QR is approximately 18.3 cm
Step-by-step explanation:
The given parameters are;
The length of the side PR = 23 cm
The length of the side PQ = 22 cm
The measure of the angle QPR = 48°
By cosine rule, we have;
Plugging in the values gives;
The length of QR ≈ 18.3 cm
I assume first equation is x-y=1. Solve for x in the first one in terms of y so you get x=y-1 so then you plug it in for x to get y-1+2y=8 then solve for y to get y=3 and then plug it into first equation to get x-3=1 and solve for x
Answer
x=4
y=3
I think hannah is correct but i may be wrong
