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.

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

$\Rightarrow m\angle PRT=m\angle PTR$

$\Rightarrow PR=PT$

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

Write the ratios for sin A and cos A. Not drawn to scale sinA= 24/10, cosA = 10/26 sinA= 24/26, cosA = 10/24

vagabundo [1.1K]

To find the values of trigonometric functions, we can use the acronym SOHCAHTOA, which stands for:

$\begin{gathered} \sin\theta=\frac{opposite}{hypotenue} \\ \\ \cos\theta=\frac{adjacent}{hypotenuse} \\ \\ \tan\theta=\frac{opposite}{adjacent} \end{gathered}$

Because we are only looking for sin A and cos A, we'll use SOH and CAH. Remember that the positions are relative to angle A. So side BC would be the opposite and side AC would be the adjacent sides.

$\begin{gathered} \sin A=\frac{24}{26}\text{ }or\text{ }\frac{12}{13} \\ \\ cosA=\frac{10}{26}\text{ }or\text{ }\frac{5}{13} \end{gathered}$

The answer is the third option, sin A = 24/26, cos A = 10/26.

Answer:

11/13

Step-by-step explanation:

take out 4 letters that it could be which are L E X and I so you have 22 letters left out of 26 so 22/26 = 11/13
