EXPLANATION.

Question = 1.

Find the length of the perpendicular drawn on x - axis from (5, -7).

As we know that,

Distance formula.

⇒ d = √[(x₁ - x₂)² + (y₁ - y₂)²].

Using this formula in this question, we get.

Coordinates on x - axis = (5, 0).

⇒ d = √[(5 - 5)² + (- 7 - 0)²].

⇒ d = √[(0)² + (-7)²].

⇒ d = √(0 + 49).

⇒ d = √49.

⇒ d = 7.

∴ The length of the perpendicular drawn on x - axis from (5, -7) is 7.

Question = 2.

What is the Co-ordinate of the point on the negative side of x - axis which is at a distance of 3 units from the origin.

As we know that,

Coordinates axis of x - axis on negative side is = (- x, 0).

Where x is the distance from the origin.

∴ The Coordinate is = (- 3, 0).

Question = 3.

The ratio of the angles of a quadrilateral is 1 : 2 : 3 : 4. find the angles.

As we know that,

Sum of angles of a quadrilateral is equal to 360°.

Let us assume that,

Angles be : x, 2x, 3x, 4x.

⇒ x + 2x + 3x + 4x = 360°.

⇒ 10x = 360°.

⇒ x = 36°.

Angles be,

⇒ x = 36°.

⇒ 2x = 2(36°) = 72°,

⇒ 3x = 3(36°) = 108°.

⇒ 4x = 4(36°) = 144°.

∴ The angles are 36°, 72°, 108°, 144°.

Answer:

kindly check my solution if u have doubts then ask me

Step-by-step explanation:

ye sab graphs analysing ke upar agr bhai ye question mcq mai hota to sirf 5 snds anwer deta bss terko

ki x axis jitna perpendicular utna mera y coordinate hoga prr mai janta hu ki terko sdpubt ayyega ki y coordinate to mai to (x,y) hota hai nhi ye galat hai khali smjh ki y coordinate only y ka value dega always remember,

next doubt hai

axis or coordinate mai diff hai

axis is plane which is formed by horizontal and vertical line , plane is two dimensional representation of any objects

define kiya hai ki vertical line ka mtlb y axis

horizontal line ka mtlb x axis
