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.

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

if the arithmetic mean of 5 and c is 11,what is the value of c?
Answers
Answer:
c = 17
Step-by-step explanation:
(c + 5) : 2 = 11
c + 5 = 22
c = 17
If the arithmetic mean of 5 and c is 11, the value of c is 17.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called average of the values of the considered data set.
It serves as predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.
If the arithmetic mean of 5 and c is 11, then the value of c.
(c + 5) : 2 = 11
c + 5 = 22
c = 17
Hence, the value of c is 17.

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.

2: Base is 25/2 (12 1/2)
3: Height is 59/4 (14 3/4)
Step-by-step explanation:
Since the formula to find the area of a pallelogram is A=base × height
I divided the area by either the Base or the height (depending which one the problem had gave me)
Therefore 147 will be divided by 15 3/4.
Then 140 5/8 will be divided by 11 1/4.
Finally 151 3/16 would be divided by 10 1/4.

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]
