The sum of the interior angles of any quadrilateral is 360°.

So,

90° + 90° + 52° + x = 360°

=> 232° + x = 360°

=> x = 360° - 232°

=> x = 128°

Answer:

x = 128

Step-by-step explanation:

All angles on a trapezoid must add up to 360 degrees. So we have 3 of our 4 angles so we can solve this as an equation

90 + 90 + 52 + x = 360

232 + x = 360

x = 128

0.86 is 3.06 % of what number (Round to the nearest hundredth.)
polet [3.4K]

Answer:

Let the number be x

3.06% = 0.0306

The above statement is written as

0.0306x = 0.86

Divide both sides by 0.0306

x = 0.86/0.0306

<h2>x = 28.10</h2>

Hope this helps you

The congruence theorem that can be used to prove △LON ≅ △LMN is SSS. ASA. SAS. HL.
Zinaida [17]

Answer:

The correct option is SSS (Side-Side-Side) Theorem

Step-by-step explanation:

The question is incomplete because the diagrams of ΔLON and ΔLMN are not given. I have attached the diagram of both triangles below for better understanding of the question.

Consider the diagram attached below. We have to find the congruence theorem which can be used to prove that ΔLON ≅ ΔLMN

We can see in the diagram that both triangle have a common side that is LN. It means 1 side of both triangles is congruent because LN≅LN

Consider the sides ON and MN. Both side have a single bar on them, which means that it is given that both of these side are congruent. Hence ON≅MN

Consider the sides LO and LM. Both side have a double bars on them, which means that it is given that both of these side are also congruent. Hence LO≅LM

SSS theorem states that if all sides of the triangles are congruent, then the triangles themselves are also congruent, which is the same case in this question
