In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved
Answer:
(15c + 8)(a + b).
Step-by-step explanation:
15c·(a+b)+8·(b+a)
(a + b) is common to both parts:
= (15c + 8)(a + b).
Answer:
27,736.5
Step-by-step explanation:
18,491 / (2/3)
When dividing by a fraction

27,736.5
Answer: 1432.752cm2
Step-by-step explanation:
Surface area of a cylinder is 2πr2+2πrh
R=12cm
H=7cm
Surface area= 2×3.142×12×12 + 2×3.142×12÷7
Surface area= 904.896+527.856
Surface area= 1432.752cm2
