Classifying Angles

Classifying Triangles by Angles

Classifying Triangles By Sides

Example: Classifying a TriangleClassify the triangle by its side lengths.The triangle has no sides of equal length. So, it is a scalene triangle.Example: Classifying a TriangleClassify the triangle by its angles and by its side lengths.The triangle has one right angle and two sides of equal length. So, it is a right isosceles triangle.

Remember that the sum of the angle measures in the triangle is 180o. This is true for all triangles.

The tables represent the functions f(x) and g(x). A table showing g(x) equals 2 x plus 15 with 2 columns and 7 rows. The first c

Maslowich

Answer:

(1) For x = –12, g (x) = -9

For x = –9, g (x) = -3

For x = –6, g (x) = 3

For x = –3, g (x) = 9

(2) The principal amount of money is $80.

Step-by-step explanation:

(1)

The expression of g (x) is,

$g(x)=2x+15$

The complete table is:

x g (x)

-15 $2(-15)+15=-15$

-12 $2(-12)+15=-9$

-9 $2(-9)+15=-3$

-6 $2(-6)+15=3$

-3 $2(-3)+15=9$

0 $2(0)+15=15$

(2)

The formula for simple interest is:

$I=P\times r\times t$

Given:

I = $40

r = 10%

t = 5 years.

Compute the value of P as follows:

$I=P\times r\times t$

$P=\frac{I}{r\times t}$

$=\frac{40}{0.10\times 5}\\\\=80$

Thus, the principal amount of money is $80.

HJ is twice JK. J is between H and K. If HJ= 4x and HK=78, find Jk.

ss7ja [257]

You'll find it easier to understand if you illustrate the problem as what is shown in the attached picture. From the illustration and the problem description, two equations can be formulated:

HJ = 2JK
HJ + JK = HK

2JK + JK = 78
3JK = 78
JK = 78/3
JK = 26
