2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
Answer:
y = 2M - x
Step-by-step explanation:
M = (x + y)/2 Multiply both sides by 2
2M = x + y Subtract x from each side
y = 2M - x

➷ At the top, the word is quadrilaterals
At the second one, the word is parallelograms
For the third layer on the left, the word is rectangles
For the third layer on the right, the word is rhombuses
Explanation:
a square is a rectangle too, and a rhombus is a shape with 4 equal sides.
Rhombuses and rectangles are parallelograms,
and a parallelogram is also a quadrilaterals.
In fact, all the shapes in the chart are all quadrilaterals.

Answer:
1/6=0.166666666666666666666666666666666666666666666667
Step-by-step explanation:
.5=1/2
half of the numbers are even
.333333333=1/3
a third of the numbers are more than 4
1/2*1/3=1/6
There is a 1/6 probability
