Find the value of x to the nearest tenth

Mathematics

Answer:

x ≈ 3.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle on the left

let third side be h , then

h² + 9² = 10²

h² + 81 = 100 ( subtract 81 from both sides )

h² = 19

Using Pythagoras' identity in the right triangle on the right

x² + 3² = h²

x² + 9 = 19 ( subtract 9 from both sides )

x² = 10 ( take the square root of both sides )

x = \sqrt{10} ≈ 3.2 ( to the nearest tenth )

Answer:

Look below.

Step-by-step explanation:

Good ol' Pythagorean Theorem.

To find the short side of the larger triangle, we'll use this equation:

a^{2} +b^{2} =c^{2} \\\\9^2+b^2=10^2\\81+b^2=100\\

You can solve the rest on your own.

Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

3^2+x^{2} = b^2

Hope it helped! Also, there seems to be a help video, if you didn't understand this explanation, why don't you go ahead and watch it?

Delmar is constructing an equilateral triangle. He uses his straightedge to draw a segment and labels the endpoints W and X. Wit
MakcuM [25]
<span>Use a straightedge to join points W and P and then points P and X. â–łWPX is equilateral. Let's see now, Delmar has a line segment WX and has drawn 2 circles whose radius is the length of WX, centered upon W and centered upon X. Sounds to me that all he needs to do is select one of the intersections of those 2 circles and use that at the 3rd point of the equilateral triangle and draw a line from that point to W and another line from that point to X. Doesn't matter which of the two intersections he chooses, just needs to pick one. Looking at the available options, only the 1st one which is "Use a straightedge to join points W and P and then points P and X. â–łWPX is equilateral." matches my description, so that is the correct choice. The other choices tend to do rather bizarre things like create a perpendicular bisector of WX and for some unknown reason, claim that bisector is somehow a side of a desired equilateral triangle.</span>
