Answer:

$\huge\boxed{\sf ST = 87 }$

Step-by-step explanation:

<u>Given:</u>

RU = TU

SU ⊥ TR

<u>To find:</u>

ST = ?

<u>Proof:</u>

ΔSTU ↔ ΔSRU

RU ≅ TU (Given)

∠SUT ≅ ∠SUR = 90° (Given that SU ⊥ TR)

SU ≅ SU (Common)

So, ΔSTU ≅ ΔSRU (SAS Postulate)

<u>Hence:</u>

ST ≅ RS (Corresponding sides of congruent triangles.)

So,

ST = 87 (Given that RS = 87)

$\rule[225]{225}{2}$

Hope this helped!

What is the area of this figure?

nalin [4]

Answer:

<em>290.5 square miles</em>

Step-by-step explanation:

Consider splitting this figure into two mini rectangles and a triangle, each of given lengths;

$Dimensions of Rectangle 1 - Height ; 5 mi, Length ; 7 mi,\\Area of Rectangle 1 - Height * Length = 5 mi * 7 mi = 35 mi^2\\\\Dimensions of Rectangle 2 - Height ; 18 mi, Length ; 8 mi,\\Area of Rectangle 2 - Height * Length = 23 mi * 8 mi = 184 mi^2\\\\Dimensions of Mini Right Triangle - Height ; 11 mi, Base ; 8 + 5 = 13 mi,\\Area of Mini Right Triangle - 1 / 2 * Base * Height = 1 / 2 * 13 mi * 11 mi = 71.5 mi^2,\\\\Area of Figure = 35 mi^2 + 184 mi^2 + 71.5 mi^2 = 290.5 square miles$

<em>Solution; 290.5 square miles</em>

The data shown on the scatter plot below demonstrates the relationship between the time of day and the total number

viva [34]

Answer:

Good question! The correct answer is a) increases and b) increases.

While the pair of answers a) decreases and b) decreases or the pair a) stays the same and b) stays the same would be technically correct answers, this is the best way of describing the trend of the scatter plot; typically, trends are described by how the dependent or y-variable responds to the independent or x-variable increasing.
