It is impossible to determine the relationship between x and y from the question about the triangle. Hence,  the correct option is D. This is because none of the sides are labelled x or y from the information provided.

<h3>What are the relationships that exist between the sides of a triangle?</h3>

It is important to note that:

The side with the highest length is the side that is opposite the biggest angle.

It is also important to note that the angle that is least will always be opposite the side that is smallest.

Two equations are given below:
astraxan [27]
A - 3b = 4
a = b -2

(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b = 4 + 2
-2b = 6
b = 6/-2
b = -3

a = b - 2
a = -3 -2
a = -5

to check: a = -5 ; b = -3  
⇒ (-5,-3)
a - 3b = 4
-5 - 3(-3) = 4
-5 + 9 = 4
4 = 4

Answer:

m<ACD = 50^{o}

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = 50^{o}

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is 50^{o}.

Which of the following represents the solution to the inequality 2 | 5 - 2x | - 3 ≤ 15
Oksanka [162]

Answer:

[-2,7] is the solution of inequality .

Step-by-step explanation:

Given :  inequality 2 | 5 - 2x | - 3 ≤ 15

To find: solution of inequality.

Solution : We have given that 2 | 5 - 2x | - 3 ≤ 15 .

On adding 3 both sides:

2 | 5 - 2x | - 3+3 ≤ 15 +3

2 | 5 - 2x |  ≤ 18.

ON dividing both side by 2 and simplify

| 5 - 2x |  ≤ 9.

On applying absolute rule,  if | u | ≤ a,a>  then -a ≤ u≤ a

-9≤5 - 2x ≤ 9.

5 - 2x ≤ 9                 ,    5 - 2x ≤ -9.

- 2x ≤ 9-5

- 2x ≤ 4

On dividing by -2

x ≥ -2.

For  5 - 2x ≤ -9.

 - 2x ≤ -9-5

- 2x ≤ -14

On dividing by -2

x ≤ 7

Therefore ,  [-2,7] is the solution of inequality .
