Step-by-step explanation:
Answer:
the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:
Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
The base angles of isosceles triangles are congruent therefore Angle c also measures 4x+6. add all 3 angles of any triangle you always get 180
3x+47 + 4x+6 + 4x+6=180
11x=121
x=11 the three angles measure 80, 50, and 50
Answer:
c. 0
Step-by-step explanation:
7 (x + 2) = 7x - 10
7x + 14 = 7x - 10
x could be anything and it wouldn't be solved.
Answer:
C.) Ordinal
D.) Nominal
Step-by-step explanation: Qualitative variables simply refers to variables of non-numeric character, nature or property. They are usually employed in assigning variables into discreet groups. The nominal and ordinal scales are employed when dealing with qualititative or categorical variables, with nominal variables used when the classes or groups involved do not follow any definite order or rank. Example include classifying sex into (male or Female), and other categorical classification of discreet nature. The ordinal scale is usually employed when dealing with ranked classifications such as level of importance[very important, Important, not so important, unimportant] or grade[distinction, excellent, very good, good, fair, poor].
