Which of the following are interior angles in the figure below?

b. < 1, < 2, and < 6

step-by-step explanation:

interior angles are those that are within the figure (in this case, the figure is a triangle). the angles within the triangle are < 1, < 2, and < 6. < 3 and < 5 are not interior angles, since they are outside the shape, and instead are called exterior angles.

hope this !

b. 1 2 and 6

step-by-step explanation:

intirior angles always hav the numbers in an enclosed shape but you have to be able to see it closed

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
