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}

The area of Miguel’s rectangular garden is 450 square feet. The garden is 9 feet wide.
Daniel [21]

Answer: 118 feet

Step-by-step explanation:

For a rectangular shape: Area = W × L

450 = 9 × L

450 ÷ 9

L = 50

Perimeter of a rectangular shape = 2L + 2W

Perimeter = (2 × 50) + (2 × 9)

= 100 + 18 = 118 feet
