A)2.8
b1) 4.5/2.8
b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees.
but if its angle BAF then the angle would be 2.8/5.3
c)41.32
-3 is actually less than -1
it can't be equal because they are 2 different values
and it can't be greater than because if you place -3 and -1 in a number Line, -1 is closer to 0 which equals that -1 is greater than -3
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
