Answer: Option D.

Step-by-step explanation:

To solve this exercise you must keep on mind the Angle at the Center Theorem.

According to the  Angle at the Center Theorem, an inscribed angle is half of the central angle.

Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:

BAC=\frac{EFD}{2}

- Solve for EFD.

EFD=2*BAC

- When you substitute values. you obtain:

EFD=2(35\°)\\EFD=70\°

explain how proving two triangles congruent can help prove parts of the triangle congruent will do branliest
AleksAgata [21]

How many facts does it take to make triangles congruent? Only 3 if they are the right three and the parts are  located in the right place.

SAS where 2 sides make up one of the three angles of a triangle. The angle must between the 2 sides.

ASA where the S (side) is common to both the two given angles.

SSS where all three sides of one triangle are the same as all three sides of a second triangle. This one is my favorite. It has no exceptions.

In one very special case, you need only 2 facts, but that case is very special and it really is one of the cases above.

If you are working with a right angle triangle, you can get away with being given the hypotenuse and one of the sides. So you only need 2 facts. It is called the HL theorem. But that is a special case of SSS. The third side can be found from a^2 + b^2 = c^2.

You can also use the two sides making up the right angle but that is a special case of SAS.

Answer

There 6 parts to every triangle: 3 sides and 3 angles. If you show congruency, using any of the 3 facts above, you can conclude that the other 3 parts of the triangle are congruent as well as the three that you have.

Geometry is built on that wonderfully simple premise and it is your introduction to what makes a proof. So it's important that you understand how proving parts of congruent triangles work.

A prom ticket at Smith high school is $120.Tom is going to save money for the ticket by walking his neighbor's dog for $15 per w
Ugo [173]
120 - 22 = 98.  98 / 15 = 6.533333.  Because you want the minimum, and he can't get paid during 0.53333 of a week,  Tom must walk the dog for a minimum of 7 weeks.

IF THE PRODUCT OF 2 FRACTIONS EQUAL 2/3 AND ONE FRACTION IS 3/5 WHAT IS THE OTHER FRACTION?
ludmilkaskok [199]
So product means multiplication
so

x times y =2/3

one is 3/5 so
x times 3/5=2/3
x times 3/5=x(3/5)=2/3
x(3/5)=2/3
multiply both sdies by 5/3 to clear fraction
x(15/15)=(2/3)(5/3)
x(1)=(2 times 5)/(3 times 3)
x=10/9
the other number is 10/9 or 1  and 1/9
