Angle A is 45 degrees.
Tan(45) = 1
Angle C is also 45, the tangent would also be 1.
Product is multiplication, so Tan A x Tan C = 1 x 1 = 1
Soz man i use the metric system
Answer:
I think it would be A.....
We are given a side of the rectangle = 11 m.
Let us assume other side of the rectangle = x meter.
We know, formula for Perimeter of the rectangle :
Periemter = 2×one side + 2× other side .
We are given perimeter = 143 m.
Therefore,
2 × 11 + 2 × x = 143
22 +2x =143.
Therefore, (d) 2x + 22 = 143 equation can be used to determine the length of the longer side of the rectangle.
B.
