Answer: The measure of angle ABC is 65 degrees.

Step-by-step explanation:

2x- 15 + 2x - 15 + x + x =360

6x - 30 = 360

+ 30 + 30

6x = 390

x= 65

check: 2(65) - 15 = 115

115 + 115 + 65 + 65 = 360

Answer:

ABC = 65

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360

2x-15 + x + 2x-15 +x = 360

Combine like terms

6x -30 = 360

Add 30 to each side

6x -30 +30 = 360+30

6x= 390

Divide by 6

6x/6 = 390/6

x=65

We want angle ABC

ABC = x

ABC = 65

The answer is "$3640.58"

Step-by-step explanation:

This question is incomplete, that's why we add another question in the attached file. Please find it.

P = $\$ \ 1300$ and effective per year is = interest rate per year = 7.2

Total $\$ \ 1300$ due after 8 years is P+PRT:

$\to 1300(1+0.072 \times 8)\\\\\to 1300(1+ 0.576)\\\\\to 1300(1.576)\\\\\to \$ \ 2048.8$

$\to Total \ X = \$ \ (7000-2048.8) \\\\$

$= \$ \ 4951.2 \\\\= X(1 +0.072 \times 5)\\\\=1.36 X \\\\$

The number of dollars is X $= \frac{4951.2}{1.36} = \$ \ 3640.58$
