Answer:

y is 70° and x is 40 °

Step-by-step explanation:

the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.

Answer:

y = 70

x = 40

Step-by-step explanation:

The interior angle connected to 110o is the supplement of the 110o angle.

180 - 110 = 70o

The triangle is marked as having 2 equal sides which means that there must be 2 equal angles opposite these 2 sides. Therefore y is also 70o

All triangles have 180o

Therefore x + y + y = 180

We know the ys = 70 each. Substitute into the equation above

x + 70 + 70 = 180                  Combine  

x + 140 = 180                         Subtract 140 from both sides.

x = 180 -  140

x = 40

If the length of the given rectangle is increased by 7 and the width is decreased by 3, what is the rectangle's perimeter
sertanlavr [38]

Answer:

For a given length l and width w, the new perimeter is....

2(l + w) + 8

Step-by-step explanation:

Currently, the rectangle's perimeter is 2(l + w). You knew that.

Now, the question asked you to change l into l + 7, and w into w - 3. Substitute them, so we get

Perimeter New = 2(l + 7 w - 3) = 2 (l + w + 4)

Then, I chose to "pull out" + 4, so I multiply it with the 2. Hence, we get

Perimeter New = 2 (l + w) + 8

What is the rate of change seen in the graph below?
eimsori [14]

Answer:

- 2

Step-by-step explanation:

Rate of change is the measure of the slope m

Calculate the slope using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (1, 0) ← 2 points on the line

m = \frac{0-2}{1-0} = \frac{-2}{1} = - 2
