x - any unit in degrees
The ratio 7 : 8, therefeor the measures of the angles are 7x and 8x.
We know: the sum of those angles is 180°
Therefore we have the equation
7x + 8x = 180
15x = 180 |:15
x = 12
The smaller angle is 7x.
Your answer is 7 · 12° = 84°
Answer:
31 copies
Step-by-step explanation:
70c+1700=3870
70c=2170
c=31
Answer:
Option D 74°
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
so
The arcs that the outer angle encompasses are
254° and (360-254)=106°
therefore
∠x=(1/2)[254°-106°]
∠x=(1/2)[148°]
∠x=74°

Answer:
He should leave by 10:30 a.m
Step-by-step explanation:
If he drives 60 miles per hr it will take him 270÷60=4.5 (4 n half) hrs to reach there.
If he want to be there at 3p.m he should leave by 10:30 a.m
