This is a 90-60-30 triangle so the angle is 30 degrees.
Answer:
5) Regular decagon. 6) Yes.
Step-by-step explanation:
Number 6 is yes bc the interior angles of a triangle have to equal 180, and 1+2+177 equals 180.
Yes it is, 6.52 and 6.52 are the same but one has an extra 0.
Answer:
height=3.28m
Step-by-step explanation:
air means volume of room
let the height of room be x.
so, volume of room= 156.1 m³
8.31*5.72*x=156.1m³
x =3.28m
To make it much easier, it should be converted to the slope-intercept form
y = mx + bTo do so, 14x + 34y = 1 turns to:
34y = -14x + 1Divide both sides by 34:
