An exterior angle of a triangle has a measure of 140 degrees. If the corresponding remote interior angles are congruent, what is the measure of each angle?
Answers
Answer:
See below, :)
Step-by-step explanation:
Hello!
From the exterior angle theorem, we know that an exterior angle is equal to remote interior angles added up. The exterior angle in this problem is 140 degrees so we also know that the remote interior angles are congruent. We can denote the interior angles as x and both combined is 2x.
Then we can create the equation:
2x = 140
x = 70
The two remote interior angles are 70 degrees.
The last interior angle is 180 - 140 = 40 degrees

The value of the variable in the given expression is 10.5.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the variable in the given expression;
[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex] divided by y.
First, we have to convert the mixed fraction into a simple fraction;
[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex]
21/2 = 12/3
Then we can write it as;
21/2 = 12/3y
y = 10.5
Hence, the value of the variable in the given expression is 10.5.

Step-by-step explanation:
P = 4s
20 = 4s
s = 5 <-- Answer for side length of Square E
P = 4s
P = 4(8)
P = 32 <-- Answer for the perimeter of Square F

Answer: The constant of proportionality is 8 for the the problem on your left! The constant of proportionality for the one on you right is 6! Hope this helps!
Step-by-step explanation: Vincent earned $24 for 3 hours and so you find out how much he gets paid for 1 hour, then you divide 24 by 3 and get 8! Later he earned $72 for 9 hours, and you do the same thing which is to divide 72 by 9 which also give you 8 and so your unit rate or constant of proportionality is 8. So for the other one Justene can bike for 12 miles in 2 hours and so you find out how many miles she can bike for 1 hours and so you divide 12 by 2 which give you 6 and she can bike 6 miles in 1 hour. Then she biked 36 miles in 6 hours and you divide 36 by 6 which give you 6 and so your constant of proportionality is 6!

Answers
Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is greater than 1.
Transformation
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor k. If k > 1, it is an increment whereas if k < 1, it is a decrease.
Given the rule:
(x, y)→(4x, 4y)
k = 4 > 1, hence this is an increase.
Trapezoid W'X'Y'Z' is larger than trapezoid WXYZ because the scale factor is greater than 1.
