Mathematics
1 answer:
Anna007 [38]2 years ago
3 0

Answer:

She used the AA theorem because the two interior angles B and D are equal to 85 degrees. ABC and EDC are equal because they are vertically opposite angles.

ABC=EDC

ABC~EDC By AA criterion of similarity

AB/ED = AC/EC Because the corresponding sides of similar triangles are proportional.
Suppose (DE) =105 ft. Calculate the distance of (AB) . Show your work. Don’t forget to label your answer.

The answer is AB= 903

105=DE 25=DC 215=CB 903=AB

105/25= 4.2

4.2 * 215 = AB=903

A man s five times as old as his son.in three years time,the product of their ages will be 380.
Mademuasel [1]

Answer:

son age: X

man_age= 5X

in 3 years: we have:  (man_age+3)(X+3)=380

we can replace the man age by 5X and we get :

(5X+3)(X+3)=380

it is a quadratic equation with 2 solutions. One negative and 7

The solution is thus 7, since age can not be negative.

The son is thus 7 and the dad 5 times more 35

Which transformations of the graph of f(x) = -4x result in the graph of f(x) = 4x +3?
Furkat [3]

Answer:

Option 1

Step-by-step explanation:

If you flip the sign on the coefficient on x, then it will be a reflection over the x-axis. The + 3 is a trick. Make sure you don't forget that you flip the sign to see the direction you are moving the graph horizontally. In this case, it would be moving to the left, so your 1st option is correct.
