Answer: 45

Step-by-step explanation:

The total degrees in a circle is 360.

The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.

so 90 + x + 3x = 90 + 4x = total

90 + 4x = 360

4x = 180

x = 45 degrees

Answer:

360=90 degrees+x+3x

360-90=270 degrees

270÷4x

67.5 degrees

The answer is x=67.5 degrees

Samir has collected 35% of the skins on Fortnite. If there are 300 total skins, how many more does he need to collect to be at 5

Nataliya [291]

I believe its 45.

Its hard to explain but what I can say is if you subtract the percentage with the total of the skins you would subtract what you had from there and then you would have 45.

The slope of the line whose equation is 5 x - 3 y = 4 is <br> 5/3 <br> 4/5 <br> -3/5

vlada-n [284]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have:

$5x-3y=4\qquad|\text{subtract 5x from both sides}\\\\-3y=-5x+4\qquad|\text{divide both sides by (-3)}\\\\y=\dfrac{5}{3}x-\dfrac{4}{3}$

The inverse of f(x)=x^2 is also a function t/f

vodka [1.7K]

The Answer is false.

the function f (x) = x 2 is NOT one-to-one, and therefore cannot have an inverse.Therefore, the function f (x) = x 2 does NOT have an inverse.
