Answer:

x = 142

Step-by-step explanation:

The problem;

\sqrt{x+2} - 15 = -3

Inverse operations;

\sqrt{x+2} -15 = -3\\                +15     +15\\\\\\\\\sqrt{x+2} = 12\\\\

Now undo the square, by squaring both sides;

\sqrt{x+2} = 12\\.^{2} \\\\\\  \\x+2 = 144

Inverse oeprations;

x + 2 = 144

  -2        -2

x = 142

The sum of the measures of the angles of a triangle is 180°. The middle-sized angle measures 3° more than 2 times the smallest a
Anit [1.1K]

Answer:

13° , 29° , 138°

Step-by-step explanation:

let x be the smallest angle , then

2x + 3 is the middle angle and

2x + 3 + 109 is the largest angle

summing the 3 angles and equating to 180

x + 2x + 3 + 2x + 3 + 109 = 180 , that is

5x + 115 = 180 ( subtract 115 from 180 )

5x = 65 ( divide both sides by 5

x = 13

2x + 3 = 2(13) + 3 = 26 + 3 = 29

2x + 3 + 109 = 29 + 109 = 138

the 3 angles are 13° , 29° , 138°

A right triangle has a hypotenuse length of 60, and one side length of 24. Do the side lengths form a Pythagorean triple? Explai
Alexeev081 [22]
You can test this using the equation: a^2 + b^2 = c^2.

24^2 + b^2 = 60^2

576 + b^2 = 3,600

b^2 = 3,024

b = 54.999

Since b is not a whole number, the side lengths do not form a Pythagorean triple.

Kryger [21]
The answer would be 60. By rounding, 14.2=14; 15.51=16; 14.99=15; 15.8=16.
14+15+16+16=61
Rounding: 61=60
