Leg 1 would be 120 ft, leg 2 would be 50 ft. use the formula a^2+b^2=c^2, a&b are legs, c is hypotenuse. sqt 16900= 130. (the issue with the question is the height of the person, but I think the question wants the hypotenuse.
Answer:
Intersection means a line common to other lines and an action of intersection/intersecting.
hope it helps!
Let's use the formula to find the perimeter of a rectangle.
2l+2w=120
We know that the length is twice its width; the equation would be:L=2w
We can plug that in to the formula.
2(2w)+2w=120
4w+2w=120
6w=120
120÷6=20=w
Since the length is twice its width, 20×2=40. The length is 40 cm.
The width is 20 cm.
Tell me if this helps!!
Answer:
Let's find the area of 1 triangle (this may not be the formula but I'm doing it in a more easier way).
20(base) x 10.5(height) = 210
210 divided by 2 ( x 1/2) = 105
Since there are 4 sides we must multiply the area of 1 triangle four times! Since there are 4 sides of triangles.
105 x 4 = 420
Oh and I almost forgot! We need to find the area of the square below!
20 x 20 = 400!
Now we add both areas of all the triangles and the area of the bottom square:
420 + 400 = 820 in2 is your answer. (we use the unit 2 since we are finding areas and adding them up)
Formula of a triangle:
BH x 1/2
B(base) x H(height) x 1/2 (basically just dividing by 2)
A matrix A is identified as
and matrix B is identified as
.If the number of columns in A is the same as the number of rows in B, then you can multiply the matrices together. The product matrix, then, is made up of what's left over: rows from A and columns from B. So your answers above are, in the first blank: columns, and in the second blank: rows.
