You could divide 100 by 4 which is 25. Then divide 69 by 4 which would bring you to 17.25. 169 divided by 4 is 42.25. The answer would be 42 with a remainder of 1
Answer:
A= 74.47
Step-by-step explanation:
you add the 24.8 to the right side to get a by itself
Use proportions because we know that the triangles are similar.

Cross multiply.
20x=28×5
x=7
answer: 7
Answer:
Step-by-step explanation:
Because CB = 6 cm, we can find CD
Use Triangle CDB.
<BCD = <BCA - <ACD
<BCD = ?
<BCA = 90
<ACD = 60
<BCD = 90 - 60
<BCD = 30
Cos 30 = CD / CB
CD = Cos(30) * BC
CD = 5.196 cm
<A = 90 - ACD
<ACD = 60
<A = 90 - 60
<A = 30
Sin(<A) = CB / AB
AB = CB / sin(<A)
AB = 6 / 0.5
AB = 12
Area =1/2 CD * AB
Area = 1/2 * 5.196 * 12
Area = 31.18
