Answer:
$15 + x = $
Step-by-step explanation:
10 times 913442 is 9134520.
Answer:
so this is trapezoid
Step-by-step explanation:
the missing length would be the height means "a"
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
