In the given the figure above, m∠BAC = 64° and m∠CBA = 56°. Part I: Find the m∠DEC. Part II: Explain the steps you took to arriv

Doss [256]

Answer:

56, see step-by-step.

Step-by-step explanation:

1. AB is parallel to CD. 1. Given

BC is parallel to DE.

m<BAC=64 and m<CBA =56

2. m<BAC + m<CBA + m<BCA =180 2. The angles in a triangle add up to 180

3. 64+ 56+ m<BCA=180 3. Substitution property of equality.

4. 120 + m<BCA=180 4. Addition property of equality.

5. m<BCA=60 5. Subtraction property of equality.

6. BC is a transversal that cuts through parallel lines AB and CD.

6. Def. of transversal.

7. m<CBA = m<BCD 7. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

8. m<BCA+m>BCD+m<DCE= 180. 8. Angle addition postulate

9. 60+56+m<DCE=180. 9.substitution.

10. 116 + m<DCE =180 10. Addition property of equality.

11. M<DCE =64 11. Subtraction property of equality.

12. DC is a transversal that cuts through parallel line BC and DE.

12. Def of transversal.

13. m<EDC= m<BCD 13. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

14. m<EDC= 60. 14. Substitution property of equality.

15. m<EDC+m<DCE+m<Dec=180. 15. Angle addition postulate

16. 56+64+m<dec = 180.16 Substitution property of equality.

17. 120+ m<dec = 180. Addition property of equality.

18. m<dec = 60 18. Subtraction property of equality.

How many solutions does 7n-3=7n+6 have?

MakcuM [25]

Answer:

Step-by-step explanation:The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. A single lap should be completed each time you hear this sound. Remember to run in a straight line, and run as long as possible.

Write the equation of the circle graphed below

Serjik [45]

Given:

Given that the circle is graphed with center (-1,1)

We need to determine the equation of the circle.

Radius:

To determine the radius of the circle, let us simply count the number of units between the center point to any point on the circle.

Hence, from the figure, it is obvious that there are 5 units between the center and any point on the circle.

Thus, radius of the circle is 5 units.

Equation of the circle:
