Answer:
96°
Step-by-step explanation:
In a cyclic quadrilateral (one inscribed in a circle), opposite angles are supplementary. That means the angles marked (6m+13)° and (4m+7)° have a total value of 180°:
(6m+13) +(4m+7) = 180
10m +20 = 180 . . . . . . . . collect terms
m +2 = 18 . . . . . . . . . . . . .divide by 10
m = 16 . . . . . . . . . . . . . . . subtract 2
∠M = 6m° = 6·16° . . . . . . . use the value of m in the expression for ∠M
∠M = 96°
Answer:
20.086
Step-by-step explanation:
Solve for x by isolating it. First subtract 25 by 19. Next, divide by 2. Finally, multiply by by base e. Use a calculator to estimate.
To find the inverse we have to first change the function notation to 'y'
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
