Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
Answer:
3 3/4 miles
Step-by-step explanation:
Mr. Connors' pattern is to drive 1 3/12 fewer miles each day. The third day after Tuesday (on Friday), he wll drive 3×(1 1/4) = 3 3/4 fewer miles than on Tuesday.
Answer:
Did you ever get the answer?
Step-by-step explanation:
OP= 27. 6
Step-by-step explanatexplanation:
In triangle OPQ: Ô+P+Q =180
therefore <P= 6°
OQ= OP sinsinà
OP= OQ/ sinà
OP= 2.9/ sin6°
OP= 27.7 ft
using pythagoras
OP^2 = PQ^2 + OQ^2
PQ= sqrt( 27.74^2 - 2.9^2)
PQ= 27.27.6
Lets say we have 7 items, and we add 7 more.
Then, in the next situation, we have 7 items and we add 8 more. Now we know that 8 = 7 + 1, so we are actually performing 7 + 7 +1. Our diagram already shows us the value of 7 + 7 so we just add 1.
The items can be represented by circles, triangles etc
