Given Trinagle ABC with A(-4, -2), B(4,4), and C(18,-8), answer the following questions.

1 answer:

8 0

For the answer to the question above, the slope of segment AC is (-6/22) = -3/11.

The slopes of perpendicular lines are negative reciprocals, so
you know that the slope of the perpendicular bisector will be 11/3.

The midpoint of segment AC is (7, -5).

Now you have the slope of the perpendicular bisector, and a
point on it. You should be able to complete the equation now.

Notice how sneaky this question is. You don't need to know
point-B at all, and you don't even need to know that there's
any triangle. All you need to know is points A and C.

What is the slant height x of the given pyramid to the nearest tenth

andreev551 [17]

The slant height, x, is 7.5 mm because you use the pythagorean formula and solve for c, since the you're solving for the hypotenuse which is the longest side.

If PQ bisects CX at point J, and if JX = 4y and CJ = y+9 find y

MAXImum [283]

Since PQ bisects CX at point J, JX=CJ

4y=y+9
-y -y
3y=9
divide by 3
y=3

Consider the two triangles.

GuDViN [60]

Answer:

(A)Show that the ratios StartFraction U V Over X Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over Z Y EndFraction are equivalent.

$\dfrac{UW}{XZ}=\dfrac{WV}{ZY}=\dfrac{UV}{XY}$

Step-by-step explanation:

In Triangles WUV and XZY:

$\angle VUW$ and \angle YXZ$ are congruent. \\\angle U W V$ and \angle X Z Y$ are congruent.\\ \angle U V W$ and \angle Z Y X$ are congruent.$

Therefore:

$\triangle UWV \cong \triangle XZY$

To show that the triangles are similar by the SSS similarity theorem, we have:

$\dfrac{UW}{XZ}=\dfrac{WV}{ZY}=\dfrac{UV}{XY}$

As a check:

$\dfrac{UW}{XZ}=\dfrac{40}{32}=1.25\\\\\dfrac{WV}{ZY}=\dfrac{60}{48}=1.25\\\\\dfrac{UV}{XY}=\dfrac{50}{40}=1.25$

The correct option is A.

If Rs 42,000 is left after paying an income tax at the rate of 30%.Find the income

Naddika [18.5K]

Answer:

Total income is 60,000

Step-by-step explanation:

I. if paid rate is 30%, that's mean 42,000 is 70%

II. Perform ratio 70/100 = 42,000/x

70*x = 100 * 42,000

70x = 4,200,000

x = 60,000

III. If you perform 30/100 = x/60,000 will be 42,000

Sorry for late.
