Answer:
5/8 ft²
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Base = 5/3 ft
Height = 3/4 ft
Area of a triangle = 1/2 * base * height
= 1/2 * 5/3 ft * 3/4 ft
Multiply numerator separately and denominator separately
= (1 * 5 * 3) / (2 * 3 * 4) ft²
= 15/24 ft²
= 5/8 ft²
Area of a triangle = 5/8 ft²
The answer would be $42.4. $50 minus $10 is $40. Multiply that by 106% because of tax, and you get $42.4.
Hope this helped! :)

Answer:
D). 290 feet
Step-by-step explanation:
Length of the yard = 65 feet
Width of the yard = 80feet
The Perimeter of the yard = 2(l + b)
= 2 * (65 + 80)
= 2 * 145
= 290 feet
∵ Fencing required = 290 feet
Thus, <u>option A</u> is the correct answer.
Since all angles in a triangle must add up to 180, let's create an equation.
angle a + angle b + angle c = 180
35 + angle b + 90 = 180
(the square at angle c represents a right angle, or an angle measuring 90 degrees)
125 + angle b = 180
angle b = 55
Final Answer: (coincidentally) angle B is 55 degrees, choice B
