Set (5x+85) equal to (11x+61) because these are vertical angles, meaning they have the same degree value.

5x+85=11x+61
subtract 5x from both sides

85= 6x+61
subtract 61 from both sides

24=6x
divide 6x from both sides

x=4

now for z, as you can see, (5x+85) and z actually create a line! and a line=180 degrees! so if we plug in 4 as the x value

5 (4) + 85 = 20 +85 = 105
180-105 = 75

z= 75

Find the first derivative of x^2+y^2=25​
lozanna [386]

Answer:

\frac{dy}{dx}=-\frac{x}{y}

Step-by-step explanation:

Use implicit differentiation:

x^2+y^2=25\\\\2x+2y\frac{dy}{dx}=0\\ \\2y\frac{dy}{dx}=-2x\\ \\\frac{dy}{dx}=-\frac{x}{y}

Remember to treat "y" as a constant in implicit differentiation and include dy/dx.

Which is a true statement about an exterior angle of a triangle?
Anuta_ua [19.1K]

Solution:

we have been asked to find the true statement about the exterior angle from the given statements.

As we know that the exterior angles are always out of the triangle and it makes a sum of 180 with anyone of the internal angle of the triangle.

The pair lies on the same straight line and makes a pair.

Hence we can say that it is formed by a linear pair with one of the interior angles of the triangle.

Hence the correct option is D.

the area of a rectangle with width x and length 7x is 7x^2 what does the coefficient 7 mean in terms of the problem
Nezavi [6.7K]
Area of figure is the total number of 1 square unit in the figure. For a rectangle, it is calculated from the product of its length and its width. For this case, we are given:

Width = x 
Length = 7x
Area = x(7x) = 7x^2

The coefficient 7 would mean that the length is 7 times longer than the width, x.
