Determine the degree measure of angle A prime

1. The angle bisector bisects the opposite side into two lengths, 2 and 4 units long.the length of the height on that side is 15 units.determine the length of the other two sides of the triangle

Rectangle P QRS and 4P QT overlap so
that R lies on QT, and RS intersects P T
at U, as shown. The area of rectangle
P QRS is 108 cm2
, and the area of 4P QT
is 81 cm2
. If the area of the figure P QT US
is 117 cm2
, determine the area of the
overlapped region, P QRU.

Two identical right-angled triangles, JKL
and MLK, overlap along side KL, as
shown. Sides JL and MK intersect at N.
The area of the overlapped region, 4KLN,
is equal to half of the area of 4JKL. The
area of the figure JKLMN is 48 cm2
. If
JK = 6 cm, determine the length of KL.
