4 0

Step-by-step explanation:

Equation of line in slope point form is given as:

y - y_1 = m(x - x_1) \\  \therefore \: y - ( - 2) = 12(x - 4) \\  \therefore \: y  +  2 = 12x - 48 \\ \therefore \: 12x - y - 48 - 2 = 0 \\ \therefore \: 12x - y - 50 = 0 \\ which \: is \: the \: equation \:  of \: \: required \:\\line.

What is the value of A? <br>5<br>5 1/3<br>6 2/3<br>7
Anna35 [415]
This is a neat little question. I don't think I've seen it before.
Step one 
=======
Find c
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5

Step 2
====
Set up your first equation for b^2
a^2 + 4^2 = b^2 from triangle XWY

Step 3
=====
Set up your second equation for b^2
25 +b^2 = (a + 3)^2 from triangle XWZ

Step 4
=====
Put the results of Step 2 into step 3 and solve
25 + a^2 + 16 = (a + 3)^2 Collect the like terms on the left.
41 + a^2 = (a + 3)^2 Expand the brackets on the right
41 + a^2 = a^2 + 6a + 9 Transfer the 9 to the left.
32 + a^2 = a^2 + 6a Subtract a^2 from both sides.
6a = 32 Divide by 6
a = 32 / 6
a = 5 2/6
a = 5 1/3
