Two right triangles always similar if

1 answer:

8 0

If the lengths of the hypotenuse and a leg of a right triangle are proportional to the corresponding parts of another right triangle, then the triangles are similar.

I really don't know how to do this-

shepuryov [24]

The sum of the interior angles of any quadrilateral is 360°.

So,

90° + 90° + 52° + x = 360°

=> 232° + x = 360°

=> x = 360° - 232°

=> x = 128°

So, for this, "x" can equal 5/2 which is fraction form, OR it can be decimal form, which would be 2.5

I hope this helps!

Find a and b if the points p(6,0) and q(3,2) lie on the graph of ax + by =12

s2008m [1.1K]

Answer:

$a= 2$

$b = 3$

Step-by-step explanation:

Given

$p(x,y) = (6,0)$

$q(x,y) = (3,2)$

$ax + by = 12$

Required

Find a and b

In $p(x,y) = (6,0)$ , $x = 6$ and $y = 0.$

This gives:

$a*6 + b*0 = 12$

$6a = 12$

Divide by 6

$a= 2$

In $q(x,y) = (3,2)$ . $x = 3$ and $y = 2.$

This gives:

$a*3 + b*2 = 12$

$3a + 2b = 12$

Substitute 2 for a

$3*2 + 2b = 12$

$6 + 2b = 12$

Collect Like Terms

$2b = 12 - 6$

$2b = 6$

Divide by 2

$b = 3$

Geometry pls help !!! Find the value of AB.<br> AB = [?]

V125BC [204]

Answer:

AB = 16 Units

Step-by-step explanation:

In the given figure, CD is the diameter and AB is the chord of the circle.

Since, diameter of the circle bisects the chord at right angle.

Therefore, AE = 1/2 AB

Or AB = 2AE...(1)

Let the center of the circle be given by O. Join OA.

OA = OD = 10 (Radii of same circle)

Triangle OAE is right triangle.

Now, by Pythagoras theorem:

$OA^2 = AE^2 + OE^2 \\10^2 = AE^2 + 6^2 \\100= AE^2 + 36\\100-36 = AE^2 \\64= AE^2 \\AE = \sqrt{64}\\AE = 8 \\\because AB = 2AE..[From \: equation\: (1)] \\\therefore AB = 2\times 8\\\huge \purple {\boxed {AB = 16 \: Units}}$
