Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
(Correct me if i am wrong)
Answer:
165 students
Step-by-step explanation:
7/4 = x/60
(60*7)/4 = 105
105 + 60 = 165
In isosceles triangle ∆ABC,
AC is the base and ADis the angle bisector of ∠A.
If ∠ADB = 110 then <ADC=70 (Linear pair of angles )
Therefore <DAC= 1/2(<DBA) (AD is the bisector of <A.)
<DAC + <DBA =180-70 =110
1/2(<DBA) + <DBA=110
<DBA=220/3 and <DAB=220/6
if <DAB=220/6 then <BAC=220/3
<ABC = 180 -(2x <BAC)= 100/3
Therefore the isosceles , ∆ABC,
<ABC=100/3, <BAC =<BCA=220/3
