Answer:

Let call the angle X

Its complement will be 90-x

Its supplement will be 180-x

(180-x)+15 = 4(90-x)

180-x+15 = 360-4x

4x-x = 360-180-15

3x = 165

x = 55

Prove

The complement of 55 is 35

And the supplement of 55 is 125

Now we must see if the relation stated holds

125+15 = 4(35)

125+15 = 140 The measure of the supplement of an angle is 15 degrees less than four times the measure of the complement.

140 = 140

Therefore the solution of the problem is given by an angle of 55 degrees.

Which values are solutions to the inequality below? √x ≤ 5
Romashka [77]
\sqrt{x}  \leq 5

Find the real  region  for \sqrt{x}

\sqrt{x} is real for x \geq 0

= x  \geq 0

\sqrt{x}  \leq 5

Square both sides:

( \sqrt{x} )^2  \leq 5^2

5^2 = 5*5 =25

Refine:

x  \leq 25

Answer D

hope this helps!

Given the following expressions:
Tamiku [17]

Step-by-step explanation:

Step 1:

A .    5 with an exponent of 3 times 5 with an exponent of -4

= 5^{3} * 5^{-4}  = 5^{3-4}= 5^{-1} = 1/5

B .   (1/4) with an exponent of 3 times (1/4) with an exponent of 2

= (1/4)^{3}  * (1/4)^{2} = (1/4)^{3+2} = (1/4)^{5} = 1/1024  

C. Same as above

D.  \\\frac{(-7)^{5} }{(-7)^{7} }  =  (-7)^{5-7}  =  (-7)^{-2}  =1/7^{2} = 1/49

Step 2 :

All the above expressions have a value between 1 and 2
