cameron is 3 years old older than karlee. karlee is two years older than denise. the sum of cameron,karlee,and denise age is 49.
Mrac [35]

Subtract 5 (Cameron) and 2 (Karlee) from 49.

Why: Denise's age is basically the basic number. Karlee would be 2 years older, so subtract 2 from 49. You get 47. Cameron is 5 years older than Denise, so subtract 5. You get 42 and divide that by 3 since there are 3 people.

49 - 7 = 42

42 divide by 3 = 14

Check:

14 + 5 = 19

14 + 2 = 16

14 + 0 = 14

19 + 16 + 14 =  49

19 (Cameron) - 16 (Karlee) = 3 years older

16 (Karlee) - 14 (Denise) = 2 years older

19 (Cameron) - 14 (Denise) = 5 years older

Hopes this helps!

Which congruence theorems can be used to prove ΔABR ≅ ΔACR? Select three options.
sergejj [24]

Answer:

1. HL

2. SAS

3. SSS

Step-by-step explanation:

Triangles ABR and ACR share side AR (hypotenuse of two right triiangles).

Angles ABR and ACR are right angles.

Sides AB and AC are congruent.

Sides BR and CR are congruent.

1. You can use HL theorem, because two triangles have congruent pair of legs and congruent hypotenuses.

2. You can use SAS theorem, because two triangles have two pairs of congruent legs and a pair of included right angles between these legs.

3. You can use SSS theorem, because two triangles have two pairs of congruent legs and  congruent hypotenuses.
