What is the value of X A 21 B 41 C 20 D 22

Mathematics
1 answer:
White raven [17]3 years ago
7 0

Answer:

22

Step-by-step explanation:

Let the bottom be y for the small triangle

So the total length of the bottom is 2y

We can use ratios to solve

x-1       1y

----- = --------

42          2y

Canceling the y's

x-1       1

----- = --------

42          2

Using cross products

2(x-1) = 42

Divide by 2

x-1 = 21

Add 1 to each side

x-1+1=21+1

x = 22

Write a similarity statement comparing the three triangles in the diagram<br> P R S Q
REY [17]

Answer:

The answer is ΔJMK ≈ ΔMLK ≈ ΔJLM ⇒ answer (A)

Step-by-step explanation:

* Lets start with the equal angles i the three triangles

- In ΔJMK

∵ m∠JKM = 90°

∴ m∠KJM + m∠KMJ = 90 ⇒ (1)

- IN ΔMLK

∵ m∠MKL = 90°

∴ m∠KML + m∠KLM = 90° ⇒ (2)

∵ m∠KMJ + m∠KML = 90° ⇒ (3)

- From (1) , (2) , (3)

∴ m∠KJM = m∠KML

∴ m∠KMJ = m∠KLM

* Now lets check the condition of similarity in the 3 triangles

- At first ΔJMK and ΔMLK

- In triangles JMK , MLK

∵ m∠KJM = m∠KML

∵ m∠KMJ = m∠KLM

∵ m∠JKM = m∠MKL

∴ ΔJMK ≈ ΔMLK ⇒ (4)

- At second ΔJMK and ΔJLM

∵ m∠KJM = m∠MJL

∵ m∠KMJ = m∠MLJ

∵ m∠JKM = m∠JML

∴ ΔJMK ≈ ΔJLM ⇒ (5)

* If two triangles are similar to one triangle, then they are

similar to each other

- From (4) and(5)

∴ ΔJMK ≈ ΔMLK ≈ ΔJLM

GenaCL600 [577]

Answer:

When x = 1, y = -2

Step-by-step explanation:

The equation of this line is y = x - 3, so when x = 1, y would equal 1 - 3 or -2.
