Answer:
Area of Rectangle = 
Step-by-step explanation:
Rectangle two vertices lie on x axis ; two vertices lie on parabola
.
Supposing coordinates of upper right vertex of rectangle are P = 
Due to parabola symmetry, width of rectangle is twice the distance horizontal (X) axis distance between Y axis & point P.
Width of rectangle = 
Length of rectangle =
; 
Area of Rectangle = Length x Width
= 
= 
= 
Answer:
ASA RULE
Step-by-step explanation:
As 2 angles are given and RV is common in both trianlges hence TVR is congruent to SRV by ASA rule
K= 10(-7) -19
k= -70-19
k=-89
