Answer:

AB≅AC (two legs of isosceles triangles are always equal)

6x-14 = 4x+20

2x-14 = 20

2x = 34

x = 17

Base ⇒ 7x-12

= 7(17)-12

= 119-12

= 107

Answer:

x=17, 107

Step-by-step explanation:

Since it is given that the triangle is isosceles, we can make the following equation:

6x-14=4x+20

x=17

To find the base (7x-12), all you have to do is plug in the value of x

7x-12

7*12-12

107

I hope this helps :)

Tyshon’s age is 3 less than three times Cedric’s age. The sum of their ages is 57. How old is Tyshon?

Airida [17]

Let Cedric's age be c
tyshon= 3c-3
3c-3 +c =3c+c-3 = 4c-3
4c-3=57
4c=60
c=15
tyshon=15×3-3 = 42

How can you use similar triangles to find a missing measurement?

Vlad1618 [11]

Answer:

By comparison of the sides.

Step-by-step explanation:

If triangles are similar, that means their angles are equal and sides are proportional.

If you already have a proportion of two corresponding sides between triangles, then use that proportion and set it equal to a side you already know the measurement to. Hopefully that side is corresponding to your missing measurement, and you can then solve it.
