Answer:

Gradient = -3
• Parallel lines have the same gradient, therefore gradient, m is -3

• At point (0, -4)

y intercept is -4

Answer:
Find the hypotenuse of the triangle, and that will help a lot!
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2 (Where c is the hypotenuse)
Here we have two leg lengths, 3 and 8.
We can put it in the formula, where it would look something like this:
3^2 + 8^2 = c^2
After simplifying, you would get that c = 
Now for the trig functions:
your adjacent leg would be 8, opposite leg would be 3, and hypotenuse 
cos θ = adj/hyp (your θ should be on the bottom left i think)
cos = 8/
sin = 7/
tan = 3/8
sec =
/8
csc =
/3
I don't know what the sixth one would be, but those are the five main ones.
Answer:
772.4 ft^2
Step-by-step explanation:
find the area of each face. first the slanted rectangle. the dimensions of the slanted rectangle are 21.7ft by 12ft. so the area is 21.7*12=260.4ft^2. for the two triangles on the sides, each on has an area of 20*8.5/2=85. next for the smaller rectangle, the dimensions are 12ft by 8.5ft giving us an area of 102 ft^2. lastly for the base, it has dimensions of 20ft by 12ft giving us an area of 240ft^2. now you just add up all the areas: 260.4+85+85+102+240=772.4 (you might want to check my addition just in case)
