There is one intercept on the graph, and I explained the process in the photo attached.
Hope it helped:)
Answer:
A. sin x = 5/13, cos x = 12/13
Answer:
There are 4 or 8 faces glued together.( it depends how you count
Step-by-step explanation:
if you take a look at the figure you see it consis of a rectangle with for cubs stcked up on one of the ends. This means the glue is in between the four cubs in the base and the stacked cubes. this means there are eight faces that have been attached since each cube is glued by one of their faces.
Step-by-step explanation:
y is easy.
it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.
so, Pythagoras :
y² = 8² + 6² = 64 + 36 = 100
y = 10
x is a bit more complex.
I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.
so, if we call the segments of the Hypotenuse a and b with a = 6, we have
x = a + b = 6 + b
height (8) = sqrt(a×b) = sqrt(6b)
therefore,
6b = height² = 8² = 64
b = 64/6 = 32/3 = 10 2/3 = 10.66666666...
so,
x = 6 + 10.66666... = 16.666666666...
round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67
