balandron [24]
Answer:
65 < or equal to x > or equal to 100

Ps: had to put "or equal to", because I can't put the lines underneath

Anyways, when an inequality says and, it is automatically a compound inequality. The x is in the middle.

The difference of two complementary angles is 48. Find the measures of the two angles.
Furkat [3]

The larger angle is 55 deg at the larger angle.

We have to know which angles are called Complementary Angles...

if we add two angles and the total will be equal to 90 deg

let's say one angle is x and  another angle is  y

as they are complementary angles from the definition we can write the equation x + y =  90

one angle is 20 deg more  than another one  so from the above condition  we write x = 20 + y

Substitute the value of x  in the first eaquation we get, 20 + y + y =  90

Then,  20 + 2y =  90

subtracting 20 from both sides,

 2y  =  90-20 = 70  

 dividing both sides by 2,

2y/ 2 = 70 / 2

 y  =  35

 So we got one angle is 35 deg

another angle is  35 + 20 = 55 deg.

Our answer is 55 deg the larger angle.

<em>Comment on this problem</em>

Understanding this representation of place value goes a long way toward understanding scientific notation. It also helps understanding of numbers written in bases other than 10.

Answer:

  x = 19

Step-by-step explanation:

The marked (consecutive interior) angles will be supplementary when the lines are parallel.

  (3x +10)° +(5x +18)° = 180°

  8x = 152 . . . . . . . . . . . . . . . divide by °, subtract 28

  x = 19 . . . . . . . . . . . divide by 8
