Answer:
Step-by-step explanation:
Mathematically, if two triangles are similar, then all the three of their angles are congruent to each other and their corresponding sides are in the same proportion. This means that the ratio of their corresponding sides are equal to each other.
Answer:
The number is divisible by 3.
Why?
Add the digits in a number together, continuing onwards until you get a 1 digit number. If this number is a multiple of 3 (3, 6, or 9), it means the original number is as well.
Try it with this number.
7 + 5 = 12
1 + 2 = 3
3 is a multiple of 3 (3*1), so 75 is divisible by 3.
Check:
75/3 = 25
25*3 = 75
Answer:
5cm
Step-by-step explanation:
Find the diagram attached.
From ΔBCD, ∠BCD = 90-∠ACD
∠BCD = 90-60
∠BCD = 30°
Also tan60 = CD/BD
tan 60 = CD/5
CD = 5tan60
CD = 5√3 cm
Similarly from ΔACD, tan30 = CD/AD
tan30 = 5√3/AD
AD = 5√3/tan30
AD = 5√3/(1/√3)
AD = 5√3 * √3/1
AD = 5 cm
Hence the length of side AD is 5cm
