Answer:

x = 63°

y = 45°

z = 72°

Step-by-step explanation:

<u>Points to remember</u>

1). Opposite angles of a parallelogram are equal

2). Adjacent angles of a parallelogram are supplementary

3). Sum of angles of a triangle is 180°

<u>To find the measures of given angles</u>

ABCD is parallelogram.

m<C = m<C = x = 63°

Consider triangle ABD

m<A + m< B + m<D = 180

x + 72 + y = 180

y = 180 - ( 72 + x) = 180 - 135

y = 45°

Also y + z + m<C = 180

45 + z + 63 = 180

z = 180 - 108

z = 72°

Find the value of x for ABCD is a parallelogram

Ilya [14]

Find parallelogram ABCD attached

Answer:

x = 3

Step-by-step explanation:

In parallelograms, the diagonals typically divide each other into 2 equal parts.

This means that from the attached parallelogram, we can say that;

4x - 6 = 2x or 6x - 15 = x

Thus;

4x - 2x = 6

2x = 6

x = 6/2

x = 3

Let's confirm with the second equation;

6x - x = 15

5x = 15

x = 15/5

x = 3

Answer:

Since you didn't mention which question.

Step-by-step explanation:

13.

$1.\overline{52}\\$ = 1.525252...

Let x = 1.525252...

10x = 15.2525252....

100x = 152.525252...

100x - x = 151.00

99x = 151

$x = \frac{151}{99}\\\\or\\\\x = 1 \frac{52}{99}$

14.

4x + 10 = 8x - 26 [ corresponding angles are congruent ]

4x - 8x = - 26 - 10

- 4x = - 36

$x = \frac{-36}{-4} \\\\x = 9$

15.

Given breadth of a rectangle is ( 2/3) its length.

Let the length be x

Therefore, breadth = ( 2 /3) of x

$= \frac{2}{3} \times x\\\\=\frac{2}{3}x$

Given perimeter = 40m

Perimeter of a rectangle = 2( length + breadth)

$40 = 2 (x + \frac{2}{3}x )\\\\\frac{40}{2} = \frac{2}{2}(x + \frac{2}{3}x)\\\\20 = x + \frac{2}{3}x\\\\20 = \frac{3x + 2x}{3}\\\\20 \times 3 = 5x \\\\x = \frac{60}{5}\\\\x = 12\\\\Therefore, Length = x = 12 \ m \ and \ breadth = \frac{2}{3}x = \frac{2}{3} \times 12 = 8 \ m$

16.

Sum of the angles of a triangle = 180°

Given ratio = 2 : 3 : 4

Sum of the ratio = 9

Therefore,

$first \ angle = \frac{2}{9} \times 180 = 2 \times 20 = 40 ^\circ\\\\Second \ angle = \frac{3}{9} \times 180 = 3 \times 20 = 60^\circ\\\\Third angle = \frac{4}{9} \times 180 = 4 \times 20 = 80^\circ$

17.

Sum of interior angles of a polygon with n sides = ( n - 2) x 180°

Given polygon is pentagon, that is n = 5

Therefore, sum of the interior angles = ( 5 - 2) x 180 = 3 x 180 = 540°

That is ,

x + 125 + 125 + 88 + 60 = 540°

x + 398 = 540°

x = 540 - 398

x = 142°
