Answer: 258
Step-by-step explanation:
86 times 3=258
If she has 10/12 and uses 8/12 then you just subtract.
Since the denominators are the same you just subtract 10-8 and get 2
the denominator is the same for your answers and so it is
2/12
Answer:
x+79degree + 35degree = 180 degree ( being the sum of all angle of the triangle )
or, x + 114 degree = 180 degree
or, x = 180degree - 114degree
or, x = 66degree
hence, x = 66 degree.
Option B: The area of the trapezoid is 157.5 m²
Explanation:
We need to determine the area of the trapezoid.
The area of the trapezoid can be determined by the formula,

where h is the height, a and b are the base of the trapezoid.
From the figure, it is obvious that
,
and 
Substituting these values in the formula, we have,

Simplifying the terms, we have,

Multiplying the terms in the numerator, we have,

Dividing, we get,

Thus, the area of the trapezoid is 157.5 m²
Hence, Option B is the correct answer.
