in the figure p is the incenter of isosceles rst what type of triangle is rpt? Thank you in advance .
snow_lady [41]

Answer:

\Delta \text{RPT is an isosceles triangle}

Step-by-step explanation:

As in the triangle RST,

RS=ST\ \ \ \Rightarrow m\angle SRT=m\angle STR

Because if in a triangle two angles equal one another, then the sides opposite the equal angles also equal one another.

Incenter is obtained by the Intersection of a triangle's three angle bisectors and it is equidistant from the three sides of the triangle.

So, RP and TP are the angle bisectors of ∠R and ∠T respectively.

\Rightarrow \dfrac{m\angle SRT}{2}=\dfrac{m\angle STR}{2}

\Rightarrow m\angle PRT=m\angle PTR

\Rightarrow PR=PT

\Rightarrow \Delta \text{RPT is an isosceles triangle}

which is a pair of dependent events? spinning a spinner one time and then spinning it a second time flipping a quarter and then
Sphinxa [80]
<h2><u>Answer and explanation:</u></h2>

Two events are said to be dependent on each other, if the outcome of the first thing affects the outcome of the second thing in such a way that the probability changes.

Here, the right answer will be = removing a marble from a bag, not putting it back, and then removing a second marble.

Explanation:

Lets suppose there were 10 marbles in the bag at the first place. Now, you removed one marble and did not put it back. So, remaining marbles will be 9. Now, if again you choose a marble, you have 9 marbles to choose from. We can see that probability changes with the event that occurred at first place.

So, this is the right answer.

Rest options are simultaneous one. They are not dependent in any way.

HELP!
adelina 88 [10]

Answer:

A) 66 inches

B) 3.5 inches

C) 38 inches

D) 3 inches

Step-by-step explanation:

A)

If the height of the 36-month-old boy is 36 inches, we just need to use the value of x = 36 in the equation, and then find the value of y:

y = 3.5 * 36 - 60 = 66 inches

B)

As the slope of the equation is 3.5, an increase of 1 in the value of x causes a increase of 3.5 in the value of y, so the answer is 3.5 inches.

C)

We just need to use y = 73 and then find x:

73 = 3.5x - 60

3.5x = 133

x = 38 inches

D)

If the increase in y was 10.5, we just need to divide this value by the slope to find the increase in x:

dx = dy/3.5 = 10.5/3.5 = 3 inches
