The perimeter is 38 , As you can see each of the sides provided also have another side across from it that’s equal to the length, therefore you you double the size of the sides that were given , and add them two together.
Actually Welcome to the Concept of the Triangles.
Since there is a linear pair with 40° , the another angle will be 140° ,
also the triangle newly formed is a isosceles one,
hence x = 20°
===> x = 20°
Now apply angle sum property of a triangle on, the other one,
we get as, 70+40+y=180
hence, y = 180-110
y = 70°
Hence angle y ==> 70°
Answer:
3. The LCD (Least Common Denominator) of the fractions
Step-by-step explanation:
This is the first step to do in order to be able to properly add the fractions.
This is true.
It comes from the same side interior angles theorem which says that same side interior angles are supplementary, only if the lines are parallel.
