First set up the equation (sum of the angles is 180)
2x + 2(x-1) + (5x +2) = 180
distribute:
2x + 2x -2 + 5x +2 = 180
combine like terms:
9x = 180
solve for x:
x = 20
SO:
2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees
check: 40 + 38 + 102 = 180
Answer:
51 degress
Step-by-step explanation:
sin x = 7/9
x = sin^-1 (7/9)
simply using a calculator.
The definition of the set E gives you a natural choice for the limits in the integral:

Computing the integral, we get



Answer:
its (
3,5) Equation form is: x = 3 , y = 5
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, simplify the equation they give you
125x+200≥1200 ---------> 125x≥1000---------->x≥8
So, x has to be greater than or equal to 8 which rules out b or d.
So the answers are narrowed down to a and c, the only difference is that the dot in A is filled in whereas the dot in c is not. In math, having a filled in circle means that value is included (≥ sign), so we will choose the answer a.
