Answer:

x + 75 = x = 15

x + 125 = x = 55

Step-by-step explanation:

to find x of a 90 degree angle and a 180 degree angle you take what you have and count up until you reach your number of 90 or 180 to get the answer of that angle

to tell what a 90 degree angle look for a right triangle or any angle below like an acute angle

to find a 180 degree angle look for an obtuse angle or the angle that creates a straight line

Answer:

x = -10

Step-by-step explanation:

x + 75 + x + 125 = 180 as supplementary (same side interior angles)
2x + 200 = 180
2x = -20
x = -10

Dragon drop each expression two correctly classify it as having a positive or negative product

ioda

Step-by-step explanation:

We multiply it to find the product

positive times positive = positive

positive times negative = negative

negative times positive = negative

negative times negative = positive

$(-\frac{1}{3})(-\frac{1}{3})= \frac{1}{9}$

Negative and negative is positive , so product is positive

$(-\frac{1}{3})(\frac{1}{3})= -\frac{1}{9}$

Negative and positive is negative , so product is negative

$(\frac{1}{3})(-\frac{1}{3})= -\frac{1}{9}$

positive and negative is negative , so product is negative

$(\frac{1}{3})(\frac{1}{3})= \frac{1}{9}$

positive and positive is positive , so product is positive

Find the area lying outside r=6cos(theta) and inside r=3+3cos(theta)

Sloan [31]

The area bounded by the 2 parabolas is A(θ) = 1/2∫(r₂²- r₁²).dθ between limits θ = a,b...

the limits are solution to 3cosθ = 1+cosθ the points of intersection of curves. 
2cosθ = 1 => θ = ±π/3 

A(θ) = 1/2∫(r₂²- r₁²).dθ = 1/2∫(3cosθ)² - (1+cosθ)².dθ 
= 1/2∫(3cosθ)².dθ - 1/2∫(1+cosθ)².dθ 
= 9/8[2θ + sin(2θ)] - 1/8[6θ + 8sinθ +sin(2θ)] .. 
.............where I have used ∫(cosθ)².dθ=1/4[2θ + sin(2θ)] 
= 3θ/2 +sin(2θ) - sin(θ) 

Area = A(π/3) - A(-π/3) 
= 3π/6 + sin(2π/3) -sin(π/3) - (-3π/6) - sin(-2π/3) + sin(-π/3) 
= π.

PLEASE HELP MEEEEE!!!!

Answer:

Step-by-step explanation:

The leading coefficient is the coefficient with a variable with the greatest exponent.The exponent is the number you would say "the power to". What I mean is let's say you have this number: $3^{2}$ . The exponent would be 2 in this equation because it's saying what power 3 is too. Therefore, 5 is the leading coefficient.
