Answer:

Step-by-step explanation:

First use the fact that the sum of interior angles of a triangle is 180° to find the measure of the missing angle

in ΔDEF we have 180 -68 -81 = 31°

in ΔABC we have 180 -68 -33 = 79°

the measure of the angles in ΔABC and ΔDEF are different 33°, 68°, 79° ≠81°, 68°, 31°so the two triangles are not congruent.

Answer:

c = -2

Step-by-step explanation:

Given equation is :

4(3+c)+c=c+4

12 + 4c + c = c + 4

A new business had a profit of $6,500 in the first month, a loss $1,200 in the second month and a loss of $1,300 in the third mo

Rufina [12.5K]

Answer:

$4000 net profit

Step-by-step explanation:

Profit adds to the net revenue, while loss subtracts from it.

So 6500 is positive but 1200 and 1300 are negative.

+6500 - 1200 - 1300 = 5300 - 1300 = 4000

$4000 profit
