Answer:
= 1
Step-by-step explanation:
tan(-x).cot(-x)
tan(-x) × cot(-x)
Note : cot =reciprocal or inverse of tan = 1/ tan
Therefore
= tan(-x) × 1/tan(-x)
= tan(-x) ÷ tan(-x)

Co ordinate of A' = (1, -4)
Co ordinate of B' = (3, 2)
Co ordinate of C' = (4, -2)
Explanation:
The figure of the triangle is shown below.
If we are finding image of the triangle about X-axis all the x -co-ordinates will remain same, but y co-ordinate will change it's sign.
So, co ordinate of A' = (1, -4)
AD = 13
Area of trapezoid ABCD

4/5
10:100=8:x
x= 100*8/10
x= 80 (80%)
80% = 80/100 = 8/10 = 4/5
-1562500
15625 × (-2) + (-15625) × 98 = -31250 + (-1531250)
= -31250 - 1531250
= -1562500
