Answer:
∠Q = 75 °
Step-by-step explanation:
Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is
∠R = ∠Q = 2x + 15
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 15 + 2x + 15 + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Hence
∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°

Answer:
Quadrilateral ABCD is a <u>parallelogram</u>
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>
Step-by-step explanation:
without solving, im guessing that quad ABCD is a paralellogram (//gram)
lets test this theory
see if the slope of AB and CD, and BC and AD is the same
slope AB and CD
AB:
-7--4/11-9
=-3/2
CD:
-1--4/11-13
=3/-2
=-3/2
slope is the same
slope BC and AD
BC:
-4--1/9-11
=-3/-2
=3/2
AD:
-7--4/11-13
=-3/-2
=3/2
slope is same
because 2 pairs // sides ---> //gram
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite
hope this helps!
please mark brainliest thank you !
