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
36+a = 2.5a
36 = 1.5a
24= a
proof: 2.5*24 = 60 = 24+36
Answer:
47.3 grams
Step-by-step explanation:
Given: A solution contains 4.3 grams of salt per liter.
To find: Amount of salt in 11 liters of the solution
Solution:
Amount of salt in 1 liter of the solution = 4.3 grams
So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams
Hence, 11 liters of the solution contains 47.3 grams of salt.
