Answer:

The answer to your question is:  ∠4 = 140°

Step-by-step explanation:

If there are two parallel lines cut by a transversal line 8 angles are formed.

These angles are classified as corresponding angles, alternate exterior angles, alternate interior angles and same-side angles.

Alternate exterior angles measure the same. Also alternate interior angles measure the same.

Same-side angles are supplementary angles, that means that their sum gives 180°.

Finally corresponding angles measure the same.

In the figure we notice that angles 6 and 8 are same side angles, so:

                                    ∠6 + ∠8 = 180

and ∠6 = 40°               40 + ∠8 = 180

                                   ∠8 = 180 - 40

                                   ∠8 = 140°

and ∠4 and ∠8 are corresponding angles so,

                       ∠4 = ∠8 = 140°

forsale [732]

The method of computing that would result in a greater finance charge is  a. the daily balance method will have a finance charge $1.02 greater than the adjusted balance method.

<h3>What is the Adjusted Balance Method?</h3>

This refers to the method of accounting that makes use of the owed amount of money at the end of a billing cycle to make its computation on an account after the credits are calculated.

Hence, we can see that when comparing the adjusted balance method to the daily balance method that calculates the interest charges at the end of the day, the daily balance method would have a higher finance charge.

Elise says, "If you subtract 17 from my number and multiply the difference by -3, the result is -61."
S_A_V [24]

Answer:

Elise's number is 112/3.

Step-by-step explanation:

You can form the equation: \left(x-17\right)\cdot -3=-61

Solution: \frac{\left(x-17\right)\left(-3\right)}{-3}=\frac{-61}{-3}

x-17=\frac{61}{3}

x-17+17=\frac{61}{3}+17

x=112/3
