Question

Find the measure of an angle which is 25⁰ less than its complement​

Answer 1

Answer:

57°30',  32°30'

Step-by-step explanation:

(x-25)+(x) = 90

2x-25=90

2x = 115

x = 115/2

x = 57°30'

90-x =  32°30'

Answer 2

Answer:

x = 77.5

Step-by-step explanation:

Given: An angle has a measurement of less than its complement.

To find the degree of angle.  

Instruction -   Let x represents the angle so make an equation that represents the value of x.

Calculation x = (180 - x) + 25

Instruction -  Remove the parenthesis and combine the like terms.

calculation

x = 180 -x 25

x = 155 - x

Instruction - Add x on both sides of the equation.  

Calculation 2x = 155

Instruction - Divide by 2 on both sides of the equation to determine the value of x.

Calculation x = 155 / 2

x = 77.5

 Final Answer

x = 77.5
