Answer the question below in the image
Ann [662]

Answer:

Both angles x and y are 69 degrees

Step-by-step explanation:

Because the angle with measure 69 degrees and angle x are alternate interior angles, they have equal value. Therefore, x has measure 69 degrees. Because this figure is a trapezoid, angle y is supplementary to the angle with measure 111 degrees. Therefore, y=180-111=69 degrees as well. Hope this helps!

Can you help with this
Komok [63]

Answer:

x = 27, and y = 47.

Step-by-step explanation:

AB is a line, so the measures of the angles measuring

2x + 1, 3x + 10, and 8/9 x + 10

add to 180 degrees. We can use that fact to find x.

2x + 1 + 3x + 10 + 8/9 x + 10 = 180

Add like terms on the left side except for the faction.

5x + 8/9 x + 21 = 180

Multiply both sides by 9.

45x + 8x + 189 = 1620

Add like terms on the left side. Subtract 168 from both sides.

53x = 1431

Divide both sides by 53.

x = 27

The angle measuring 3x + 10 is vertical with the angle that is made up of the measures y - 3 and y. Therefore, the sum of the measures y - 3 and y equals the measure 3x + 10. We know x, so we can find 3x + 10.

3x + 10 = 3(27) + 10 = 91

Now we set the sum of y - 3 and y equal to 91 and solve for y.

y - 3 + y = 91

2y - 3 = 91

2y = 94

y = 47

x = 27, and y = 47.

The length of two sides of triangle are 4cm and 5cm. Between what two
Elanso [62]

Answer:

1 and 9

Step-by-step explanation:

By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.

In other words, in a triangle with side lengths a, b, and c, we always have a+b > c.

Applying this to this question, the other side length, x, must satisfy the following inequalities:

4+5 > x,\\x+5 > 4,\\x+4 > 5.

Solving these inequalities gives

x < 9,\\x > -1,\\x > 1.

Combining these solutions, we have 1 < x < 9. Therefore, the length of the third side falls between 1 and 9.
