Turn the improper fraction 2(3/4) into a mixed fraction by multiplying the coefficient or outside number "2" by the denominator "4" and then adding that result with the numerator "3":

2*4 = 8

8 + 3 = 11

Leave the denominator fixed and put you previous result as the numerator; your new fraction is 11/4

Now multiply this with 4/5:

11/4 * 4/5 = 44/20 = 22/10 = 11/5 (simplified result)

Now convert this simplified mixed fraction back into an improper fraction:

You divide the denominator "5" into the numerator "11" and put the most amount of times it goes into it out front as the coefficient;

We get that 5 goes into 11 a maximum number of times which is 2.

Then subtract the numerator "11" from "10" (5 *2) and we get 1.

Our answer is 2(1/5)

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
