Answer:
√41
Step-by-step explanation:
Use the distance formula.
(3, 1) and (-2,-3)
The distance between 3 and -2 is 5. 5 squared is 25.
The distance between 1 and -3 is 4. 4 squared is 16.
25+16 = 41
the root of 41 is √41.
Answer:
BCDE is inscribed quadrilateral. the opposite angles of a quadrilateral add up to 180°
<E = 84-180= 96°
ans is 96°

Answer:
Length of the fence required = 135 m
Step-by-step explanation:
Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid
Perimeter of ABCD = AB + BC + CD + AD
Since, AB = BC = EF = ED = 25 m
From the given right triangle BEC,
m∠EBC = m∠ECB = 45°
ΔBEC will be an isosceles triangle.
So, BE = EC
By Pythagoras theorem,
BC² = BE² + EC²
25² = 2(EC)²
EC =
m
And DC = (DF + EF + EC)
= EC + EF + EC [Since, DF = EC]
= 2EC + EF
= 35.4 + 25
= 60.4 m
Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25
= 135.4 m
≈ 135 m
Therefore, length of the fence required = 132 m
