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!

The triangles in the figure are similar: ΔABC ∼ ΔDEF. Which of the following statements must be true? options: A) AB/DE=BC/EF=CA

VikaD [51]

Answer:

Answer A

Step-by-step explanation:

We see that ABC is similar to DEF. Pay attention to the order of these letters. The order that they read (left-to-right) is the order that they are similar. For example, AB is similar to DE. Despite being different triangles, they are both the <em>first two </em>letters in the triangle. So, knowing this, we can conclude that answer choice A is correct.

What is the value of the expression below when y=6y=6? y^2 -5y-4 y 2 −5y−4

Elodia [21]

Answer:

2

Step-by-step explanation:

Given expression:

y^2 - 5y - 4

y = 6

Substitute y = 6 into the expression

y^2 - 5y - 4

6^2 - 5(6) - 4

(6*6) - (5*6) - 4

36 - 30 - 4

36 - 34

2

The value of the expression y^2 - 5y - 4 is 2 when y = 6

Darren is painting a wooden block as part of his art project The block is a rectangular prism that is 12cm long by 9 cm wide by

Ksenya-84 [330]

Answer:

<h3>The surface area in square meters that Darren has to paint is $426cm^2$ </h3><h3>∴ $A=426cm^2$ </h3>

Step-by-step explanation:

Given that Darren is painting a wooden block is a rectangular prism

Its length is 12 cm ,width is 9 cm and height is 5 cm

<h3>To find the surface area in square meters that Darren has to paint :</h3>

Let l be the length, w be the width and h be the height

Then l=12 cm , w=9 cm and h=5 cm

The formula for the Surface area is

A=2(lw+wh+hl) square units

Substitute the values in formula we get,

A=2(12(9)+9(5)+5(12))

=2(108+45+60)

=2(213)

=426

<h3>∴ $A=426cm^2$ </h3><h3>∴ the surface area in square meters that Darren has to paint is $426cm^2$ </h3>
