Answer:
m∠ABC = 83°
Step-by-step explanation:
The angle ∠abc and ∠dbe are opposed by the vertex. By definition "<em>Two angles opposite the vertex are congruent or equal</em>"
So ∠abc = ∠dbe
Then, to solve this problem you must match both expressions and clear the variable x.

Now substitute x = 15 in the given expression for the angle ∠abc. (6x-7)
So, we have:
°
Finally, the angle is 83°
Multiplying the number by 1,000
Answer:
D
Step-by-step explanation:
The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.
The entry in the
row (start counting rows from 0) and
column (start counting columns from 0) of Pascal's triangle is denoted by

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.
Hence,

Answer:
7.5
Step-by-step explanation:
If we look at the 4 by 4 square around the triangle we can just do the area of the square minus the area of the 3 little triangles which is:
4 * 4 - 4 * 1 / 2 - 3 * 3 / 2 - 4 * 1 / 2
= 16 - 2 - 4.5 - 2
= 16 - 8.5
= 7.5
