SOMEONE PLZZZ HELP ME THIS IS DUE IN LIKE 5 MINS (I WILL MARK BRAINLIEST)
andrew-mc [135]

Answer:

1) x = 8

2) ∠RPS = 36°

Step-by-step explanation:

<u>GIVEN :-</u>

  • ∠QPS = 180°
  • ∠QPR = 7x + 88
  • ∠RPS = 3x + 12

<u>TO FIND :-</u>

  1. Value of x
  2. Measure of ∠RPS

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.

<u>PROCEDURE :-</u>

1)

Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.

⇒ ∠QPR & ∠RPS are linear pair.

⇒ ∠QPR + ∠RPS = 180°

⇒ 7x + 88 + 3x + 12 = 180°

⇒ 10x + 100 = 180

⇒ 10x = 180 - 100 = 80

⇒ x = 80/10 = 8

2)

x = 8. So,

∠RPS = 3×8 + 12 = 24 + 12 = 36°

Choose the polynomial written in standard form.
Semenov [28]

Answer:

x^4 + 4x^3 + 10x

Step-by-step explanation:

A polynomial written in decreasing order of the degree of its monomials ( or single term ) is called its standard form,

In polynomial,

x^2 + 4x^4 + 10x^6,

Degrees are written in increasing order,

⇒ It is not written in standard form,

In polynomial,

x^4 + 4x^3 + 10x,

Degrees are written in decreasing order,

⇒ It is written in standard form,

In polynomial,

x^7 + 4x^3 + 10x^4,

There is no order of degrees,

⇒ It is not written in standard form,

In polynomial,

x^6 + 4x^3 + 10x^7,

There is no order of degrees,

⇒ It is not written in standard form,
