Answer:

-14

Step-by-step explanation:

3(y-1)=y-11

3y-3=y-11

y=3-11

y= -14

Multiply 3 into (y-1)

Then substitute 3 for Y

bringthe 3 over the equal sign to y

3y-3 = -3-11

y = -14

3(y-1)=y-11

Distribute:
3y - 1 = y- 11

Add 11 to both sides

3y - 12 = y

subtract 3y on both sides

-12 = -2y

Divide by 2y

y= 6

Find the value of x. Diagram not to scale

We first need to find the sum of the interior angles in a pentagon, which you do by doing (5 - 2) × 180, which equals 3 × 180 = 540°. Now you know that all of the angles inside the shape must add up to 540, so you can make an equation:
90 + 112 + 2x + 148 + 2x + 10 = 540
360 + 4x = 540
- 360
4x = 180
÷ 4
x = 45

I hope this helps!

Answer:

  1. 33.0 m
  2. 26.1 mi
  3. 28.0 mi
  4. 33.0 mi

Step-by-step explanation:

In each of these Law of Sines problems, you are given side a and angles B and C and asked for side c (problems 1, 3, 4) or side b (problem 2). The solution is basically the same for each:

Find the missing angle. Find the side from ...

  c = a·sin(C)/sin(A)

__

1. angle A = 180°-89°-58° = 33°

  c = (18 m)sin(89°)/sin(33°) ≈ 33.0 m

__

2. angle C = 180°-13°-17° = 150°

  b = (58 mi)sin(13°)/sin(150°) ≈ 26.1 mi

__

3. angle A = 180°-61°-89° = 30°

  c = (16 mi)sin(61°)/sin(30°) = 28.0 mi

__

4. angle A = 180°-39°-127° = 14°

  c = (10 mi)sin(127°)/sin(14°) ≈ 33.0 mi

Segment AB is all points on the line between the endpoints A and B<br><br> True or false
fredd [130]
False because if it is a segment, it would only have two points at the ends so if there is points between the ones at the ends then it is multiple segments

In this PARALLELOGRAM, what is the measure of Angle D?
enot [183]

Answer:

92

Step-by-step explanation:

The parallelogram is divided into two triangles. Remember, angles in a triangle add up to 180 degrees. That being said, take the sum of the numbers given in triangle ABC and subtract it from 180.

60 + 28 = 88

180 - 88 = 92 (this is the measure of angle B)

Angles D and B are congruent, which means they are the same.

Since Angle B is 92 degrees, then D is 92 degrees also.
