Answer:
First. 115°
Second. 65°
Third. 65°
Fourth. 7
Fifth. 425.25
First
angle DAB = angle ADC (since this is an isosceles trapezoid)
Second
In a trapezoid adjacent angle are supplmentary (that is their sum is 180°)
180-115 is 65°
Third
(Same reason as second)
Fourth
The side 3x+4 is same as the opposite side
So 3x + 4 = 25
on solving you get x = 7 in
Fifth

area = 1/2 × 13.5 (20+43)
area = 1/2 × 13.5 × 63
Thus area is 425.25
<span>In this equation, 36>11 and so the ellipse has major axis along x axis
standard equation of ellipse with major axis is along x axis
x^2/a^2+y^2/b^2=1,
the foci are at (ae,0) and (–ae,0)
eccentricity e is given by
ae=√(a^2-b^2)
In this case ae=√(36-11)= √25=+/- 5
Focii are(-5,0) and(5,0) </span>

Answer:
x degree = 112 degree
Step-by-step explanation:
let the intersecting point of two cords be O.
then arc QR = angle QOR
which means ; 68 degree = angle QOR
Now,
angle QOR + angle POQ = 180 degree ( linear pair )
or, 68 degree + angle POQ = 180 degree
hence, angle POQ = 112 degree,.
