Answer:
Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the smallest angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
one angle is 130 degrees more than the smallest angle
----> equation B
the third angle is 3 times as large as the smallest angle
---> equation C
substitute equation B and equation C in equation A
solve for y
Find the value of x
Find the value of z
therefore
Answer:
The second and fourth options
Step-by-step explanation:
A function is where one the inputs have only one output. In this case all we have to do is look at the x value (x,y) and see when it goes 1,2,3,4 and that means there are no repeating x and in that case each input has only one output. If you look at the other ones they have a repeating x and that means the input has two outputs and therefore it isn't a function.
Answer:
Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio (in other words, if they are proportional). Typically, problems with similar polygons ask for missing sides.

Answer:
She can make 16 necklace and beads left 4
Step-by-step explanation:
Emma has 148 beads
Each necklace has 9 beads
148 ÷9 =16. 44 necklace
16 necklace
Beads left
16 *9
144
148 - 144
4 beads left
Answer:
Addition Property of Equality
Step-by-step explanation:
Given expression:
To find the missing justification.
We will evaluate the given expression and justify the step.
Using Addition Property of Equality( by this property of equality we can add a number to both sides of the equation without effecting the equality of the equation)
Adding to both sides of the equation.
