Answer:
Below.
Explanation:
10.
a) RT is a half of RG so RG = 18 x 2 = 36 (if you’re asking why, search up the properties of a rectangle.)
b) HI = RG (if you’re asking why, search up the properties of a rectangle.)
—> 4x + 12 = 10x - 15
—> 27 = 6x —> x = 27/6 = 4.5
11. Since this is a parallelogram —> angle PSR = angle PQR (if you’re asking why, search up the properties of a parallelogram.)
We also have PS = QR and PQ = RS (if you’re asking why, search up the properties of a parallelogram.)
In triangles PQR and RSP:
QR = SP (from above)
PQ = SR (from above)
<PSR = <PQR (from above)
—> Triangle PQR and triangle RSP are congruent (side angle side)
