IN PARALLELOGRAM BCHS IF BC = 15, BS = 12, and SH = (3x - 3), WHAT IS THE VALUE OF THE VARIABLE x?

Answers

Answer:

6

Step-by-step explanation:

Given a parallelogram BCHS

Opposite side of the parallelogram are equal hence;

BC = HS

Given

BC = 15, BS = 12, and SH = (3x - 3),

15 = 3x-3

3x = 15+3

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

plz help.................

Answers

1) question 1 has been done for you

2) step one: square the two numbers that aren’t the hypotenuse(the longest side-opposite the right angle).
Step two: add the two numbers together
Step three: square the hypotenuse

If the two values squared and added together equal the hypotenuse squared then it is a right angled triangle.

3) a triangle with the side lengths of 11cm, 13cm and 15cm wouldn’t be a right angled triangle.

Because 11^2 + 13^2 = 290 and 15^2 = 225, therefore it isn’t a right angled triangle because 290 doesn’t equal 225.

Line BD is tangent to a circle with diameter AB. Explain why the measure of angle BCA must equal the measure of angle ABD.

Answers

Answer:

This is because angles inscribed in a semicircles are 90 degrees (BCA)

The tanget of that circle is also a 90 degree angle to the diameter (ABD)

Therefore they're both 90 degrees

The measure of angle BCA must equal the measure of angle ABD should be that angle should be  inscribed in a semicircles that are 90 degrees,

What is the inscribed angle?

In terms of geometry, an inscribed angle refer to the angle that should be created in the interior of a circle  at the time when two chords should be intersect on the circle. It can also be refer to the angle subtended at a point on the circle via two given points on the circle.

Also, angle should be  inscribed in a semicircles that are 90 degrees,

PLEASE HELPP

Answers

Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = [tex]126^{o}[/tex]

we know,

          exterior angle = sum of interior non adjacent angle

   so,   [tex]126^o[/tex] = [tex]x + 90^o[/tex]    [∵ one angle of right angled triangle is [tex]90^o[/tex]]

     or,  [tex]x = 126^o - 90^o\\[/tex]

     or,  [tex]x = 36^o[/tex]

hence, the value of x is [tex]36^o[/tex]
