x = 180 - 118 ( linear angles)

x = 62

62+62+y = 180

y = 56

Answer:

Step-by-step explanation:

Angle of a straight line = 180 degrees :)

So to find x you would do:

x = 180 - 118 = 62

Also the angle sum of a triangle = 180 degrees.

Since it is an isosceles triangle, the bottom two angles would be equal:

Angle sum of triangle = 180

x + x + y = 180

Since we know x = 62, substitute it into the above equation:

62 + 62 + y = 180

124 + y = 180

Subtract 124 from both sides to solve for y.

y = 180 - 124

y = 56

If F(x) = 9x, which of the following is the inverse of Fx)?
Arturiano [62]

Answer:

F⁻¹(x) = x/9

Step-by-step explanation:

To find the inverse of a function, you want to switch x and y in the equation and solve for y.

F(x) = 9x

x = 9F(x)

x/9 = F⁻¹(x)

Therefore, the inverse is F⁻¹(x) = x/9.

- 4. What is the roster form of the set K = {x/x are odd numbers from 2 to 8} ? A. H = {2, 4, 6, 8} C. H = {3, 4, 5, 6, 7} B. H
tangare [24]
<h3>Answer:  H = {3, 5, 7}</h3>

Explanation:

We simply list any odd number that is between 2 and 8. The term "roster form" can be thought of as listing the roster of a sports team (eg: baseball). So instead of describing what the numbers look like, we list out the numbers themselves. Those numbers being 3, 5 and 7.

Something like {2,4,6,8} is ruled out because we're dealing with odd numbers only.

Iteru [2.4K]

Answer:

x = 50°

Step-by-step explanation:

sum of all angles of a quadrilateral is 360°

so, the other unknown angle be y

=》y + 40° + 110° + 80° = 360°

=》y + 230° = 360°

=》y = 360° - 230° = 130°

and the unknown angle + x = 180°

( because they for linear pair )

so, x + y = 180°

x + 130° = 180°

x = 180° - 130° = 50°

hence, x = 50°
