Find the measure of each angle. Assume the lines are parallel, I dont have a protractor small enough to do this job.

Sholpan [36]

Answer:

All angles are 113 or 67. See below for each angle measure.

Step-by-step explanation:

Parallel lines cut by a transversal have several angle relationships which can be used to find an unknown angle measure:

• Alternate Interior Angles are angles across the transversal between pairs of parallel lines. These angles are congruent. Example: 8 and 4 are congruent and are pairs of alternate interior angles. 7 and 3 are another set.

• Alternate Exterior Angles are angles across the transversal outside of the parallel lines. These angles are congruent. Example 1 & 5 are congruent alternate exterior angles. 2 and 6 are another set.

• Supplementary angles are angles which form a line and add to 180. If angle 1 + angle 2 = 180 and angle 1 = 113, then 113 + Angle 2 =180. Angle 2 must be 67 degrees.

• Vertical angles are angles across a vertex. They are congruent. Example: Angle 2 and Angle 8 are both 67.

Using these relationships, the following angles have the following measures:

Angle 1 = 113

Angle 2 = 67

Angle 3 = 113

Angle 4 = 567

Angle 5 =113

Angle 6 = 67

Angle 7 = 113

Angle 8 = 67

Jenny wants to rent a truck for one day. She contacted two companies. Laguana’s Truck Rentals charges $20 plus $2 per mile. Salv

zlopas [31]

Answer:

The total cost will be the same for both companies after 20 miles.

Step-by-step explanation:

First, I wrote the equations:

Laguna's Truck Rentals: 2x + 20

Salvatori's truck rentals: 3x

To find when the total cost for both companies will be the same, I kept substituting numbers for the variable until it worked. So, the total cost for both companies will be the same after 20 miles. Hope this helped!

A quantity with an initial value of 6200 decays continuously at a rate of 5.5% per month. What is the value of the quantity afte

ELEN [110]

Answer:

410.32

Step-by-step explanation:

Given that the initial quantity, Q= 6200

Decay rate, r = 5.5% per month

So, the value of quantity after 1 month, $q_1 = Q- r \times Q$
