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

Find the area of a triangle with the given vertices.
Cerrena [4.2K]

Answer:

the area of the triangle is <u>4 square units.</u>

Step-by-step explanation:

Plotting the points, we can see that the triangle is isosceles lying in the 4th quadrant of graph.

we can break the triangle in 2 similar right angled triangles,

each with base 2 and height 2  units.

area of triangle is given by the formula,

A= (\frac{1}{2})(base)(height)

thus, A= (\frac{1}{2})(2)(2)

A=2 square units.

there are 2 such triangles,

thus total area is 4 square units.

^4√4y =4-3

^4√4y = 1

^4√4y =^4√1

so, 4y = 1

y = ¼

how are the steps to solving an inequality similar to those for solving an equation? how are they different
juin [17]
<h2>Similarities:</h2>
  • With both inequalities and equations, you are solving for a variable by isolating it to one side.
  • A lot of properties that apply to equations apply to inequalities as well (addition property of equality, division property of equality, etc.)
<h2>Differences:</h2>
  • If you divide or multiply by a negative number, you must flip the inequality symbol. Dividing or multiplying by a negative number doesn't affect the equal sign.
  • When graphing the inequality, shaded regions (and the lines themselves if they're solid lines) are a part of the solution. When graphing an equation, only points on that line are solutions.
