All angles of a triangle added together equal 180 degrees
180=(6x-1)+(x+14)+(20) which simplifies to 180=7x+33
next, solve for x by subtracting 33
147=7x
then solve by dividing by 7
21=x
plug x back into your original equations to find the angle measures
A=6(21)-1 A=125 degrees
B=(21)+14 B=35 degrees

Examine the diagram. A triangle has angles A, 15 degrees, 80 degrees. The exterior angle to angle A is B. What is the sum of the

QveST [7]

Answer:

m<A = 30degrees

m<B = 70degrees

Step-by-step explanation:

Find the diagram attached

From the diagram;

m<A + 150 = 180

m<A = 180 - 150

m<A = 30degrees

Also since the sum of angles in a triangle is 180degrees, hence;

m<B+m<A + 80 = 180

m<B+30+80 = 180

m<B+110 = 180

m<B = 180 - 110

m<B = 70degrees

Check all of the functions that are odd.

Elan Coil [88]

For a function to be odd f(-x)=-f(x).

1) putting x as -x

f(-x)= -x^3+x^2 = -f(x)

Thus, this is an odd function.

2) Following the same procedure,

f(-x)= -x^5+3x^3-2x =-f(x)

Thus, this is an odd function.

3) Again,

f(-x)= -4x-9 = -f(x)

This also is an odd function.

Hope this helps :)
