nasty-shy [4]3 years ago
5 0

Answer: 1. False.

2.True.

3.True.

4.False.

5.True.

6.False.

Explanation:

1.∠XFG is lying between the one side and the line extended to the next side of the triangle, therefore it is an exterior angle.

2.∠EFG is lying between the two sides of the ΔEFG, therefore it is an interior angle of the triangle.

3.∠FEZ is lying between the one side and the line extended to the other side of ΔEFG.

4.∠YGE is a straight line it is between the one side and the line extended to the same side ∴ it cannot be an exterior angle of the triangle.

5.∠EGF and FGY lying on the same line YZ ,∴they are linear pair i.e. they are supplementary angles.

6.∠FEG and ∠FGE are both the interior angles of a triangle and we know that for supplementary angles they should lie on the same line.Therefore ∠FEG and ∠FGE are not supplementary angles.

1) ∠XFG is an interior angle of ΔEFG. - False

(∠XFG is an exterior angle of ΔEFG since that angle is out of the triangle)

2) ∠EFG is an interior angle of ΔEFG. - True

(∠EFG is an interior angle since it is included in the ΔEFG)

3) ∠FEZ is an exterior angle of ΔEFG. - True

(∠FEZ is an exterior angle as it it is out of the triangle EFG)

4) ∠YGE is an exterior angle of ΔEFG. - False

(∠YGE is not an exterior nor an interior angle since it is a straight line)

5) ∠EGF and ∠FGY are supplementary angles. - False

(∠EGF and ∠FGY do not add up to 180° so they are not supplementary)

6) ∠FEG and ∠FGE are supplementary angles. - False

(∠FEG and ∠FGE do not add up to 180° so they are not supplementary)

X=5-3Y<br> X=2Y-10<br> Whats the answer
prohojiy [21]
X = 5 - 3y
x = 2y - 10

5 - 3y = 2y - 10
<u>  + 3y + 3y        </u>
       5 = 5y - 10
  <u>+ 10        + 10</u>
     <u>15</u> = <u>5y</u>
      5      5
       3 = y
x = 2y - 10
x = 2(3) - 10
x = 6 - 10
x = -4

You have decided to purchase a car for $22,346.16. The credit union requires a 10% down payment and will finance the
sukhopar [10]

Answer:

(b) \$24,169.60

Step-by-step explanation:

Given:  Cost of car is \$22,346.16

            Sales tax is 7.6\%    

             The license and title  charges are \$125.13

To find: The amount that the credit union will finance.

Solution:

We have,  

Cost of car=\$22,346.16  

Sales tax is 7.6\% of \$22,346.16

Therefore,  

sales tax =\frac{7.6}{100}\times22,346.16=\$1698.31

The license and title  charges =\$125.13

Now, the amount that the credit union will finance is

cost of car+sales tax+the license and title  charges

=\$22346.16+\$1698.31+\$125.13

=\$24,169.60

Hence, the amount that the credit union will finance is \$24,169.60.

So, (b) \$24,169.60 is correct.
