1. Use the exterior angle theorem that states that an exterior angle in a triangle is equal to its two remote interior angles.

x+46=84

x=38 degrees

2. There are two parallel lines cut by transversal. We can see a same side interior relationship.

3x-5+90+2x=180

5x=95

x=19 degrees

3. Use exterior angle theorem again.

90+34=x+72

x=52 degrees

What additional information would you need to prove that triangle ABC is congruent to triangle DEF by ASA
Lostsunrise [7]
Of two angles and the included side of one triangle are congruent to the corresponding to the corresponding parts of another triangle hen the triangles are congruent. I really don't think there is additional information to prove if the triangles are congruent by using ASA.

Susie has a bag with 8 hair pins, 7 pencils, 2 snacks, and 4 books. What is the ratio of books to pencils?
Viefleur [7K]
<h3>Hello there!</h3>

The first thing we need to do here is see which information is relevant.

The question is asking for the ratio of books to pencils.

Therefore, we only need the number of books and pencils - all other information given is irrelevant in this scenario.

Number of books - 4

Number of pencils - 7

Now, we can order this as a ratio.

A ratio is two numbers put as a proportion. It's normally written out as first number : second number.

In this case, it's the ratio of number of books : number of pencils.

Fill in the number of books and number of pencils into each side of the equation.

number of books : number of pencils

4 books : 7 pencils (the unit is normally dropped)

So therefore, 4:7 would be your final answer.

Hope this helped!
