D. 30* Because This is definitely smaller than a 45 degree angle. If it was a bit wider it would be.
I won't tell you the answer but I'll tell you how to do it
first, find the area of the rectangle (lxw)
Next, find area of the triangle (BxHx.5)
Then, subtract the area of the rectangle to the area of the triangle
4y=3x-24
y=3/4x-6
the line intersect x axis in A
y=0, 3/4x=6, 3x=24, x=8 ⇒ A (8,0)
the line intersect y axis in B
x=0, y=-6 ⇒ B (0,- 6)
a.the gradient of l is 3/4
b. AB= V 6^2 +8^2=V36+64=V100=10
First, simplify the given expression: combine 1 and 9 to get 10.
Then the problem reduces to 1/3 + 1/4 + 10.
The LCD of these two fractions is 12, and so, after conversion to LCD 12, we get
4+3
----- + 10 => 10 7/12, or 127/12
12
The answer is 1.48226407 hope it helps
