What’s the missing angle. Brainliest if your correct

stellarik [79]

We are given:

We know that the sum of all interior angles of a Pentagon is 540°

we are given 4 out of the 5 angles

Solving for x:

since the sum of all 5 angles is 540°:

75 + 130 + 135 + x + 90 = 540

x + 430 = 540

x = 540 - 430

x = 110°

<h3>Answer 1 :-</h3>

If I were one of the students in Barangay then I shall prepare the design of kite by using the known properties of kites in mathematics.

For example, Symmetrical about its main diagonals, Adjacent side equals, Having two pairs of congruent triangle etc.

<h3>Answer 2 :- </h3>

Design of kite assign to me

Step 1 :-

I shall take one paper and cut it like that the adjacent sides of paper are equal

Reason :-

Adjacent sides of kite are equal

Step 2 :-

I shall take two thin sticks and paste it on the paper but sticks should intersect each other at 90°

Reason :-

Kite has 2 diagonals which intersect each other at 90° .

Step 3 :-

Make a hole in the one of the end point of a longest sides.

Observation :-

The kite should be looked like that it having two pairs of congruent triangle with common base.

<h3>Answer 3 :-</h3>

The adjacent sides of the kites are equal that is 4cm and 6cm
The diagonals of the kite bisect each other at 90°
As kite is symmetrical from main diagonals , so it has two opposite and equal Angles that is 127°
The opposite angles at the end points of kite are congruent that is Angle D and Angle C
AC is the bisector of AB and AB is the bisector of AC .

[ Note :- Kindly refer the above attachment ]

<h3>Answer 4 :-</h3>

All mathematical concepts used in making kite are as follows :-
