Answer:
x = 16°
Step-by-step explanation:
The three internal angles of the triangle are:
180° - 91° = 89° (angles in a straight line)
180° - 105° = 75° (angles on a straight line)
x = x (vertical angles are congruent)
x + 89 + 75 = 180 (sum of interior angles of a ∆)
x + 164 = 180
x = 180 - 164 (subtraction property of equality)
x = 16°
8) a regular dodecagon has 12 equal sides. So if one side is 9.25 cm, a formula we can use is:
P = 12*9.25, which is:
P = 111 cm
9) A rhombus has four equal sides, so a formula we can use is:
P = 4*1.75, which is:
P = 7 yd
10) A paralleogram has four sides where opposite sides are equal, so a formula we can use is:
P = 2*10.4 + 2*5.6, which is:
P = 32 m

if i am reading this question correctly you are asking how much farther mike lives from sam.
30-8=22
this is pretty easy, just simple subtraction.
Answer: x=-12
Step 1: Simplify both sides of the equation.
4x+27=−33−x
4x+27=−33+−x
4x+27=−x−33
Step 2: Add x to both sides.
x+27+x=−x−33+x
5x+27=−33
Step 3: Subtract 27 from both sides.
5x+27−27=−33−27
5x=−60
Step 4: Divide both sides by 5.
x=−12
