Question

An isosceles triangle has base angle of 30' and base 10√3cm long. What is the height of this tringle
What is the length of the two equal sides?​

Answer 1

Answer:

lengh is 4cm

• Step-by-step explanation
• 10÷2=5
• area of a isoceles triaangle is
• 1/2×b×h
• the height is 3cm
• the base I divided into two which I got 5 cm
• do the a² +b²=c²
• 5²=25
• 3²=9
• 25-9=16
• √16
• is 4cm
• so the side which is 4cm will be the one side so both side will be 8cm=4+4

Answer 2

Answer:

it is 5 cm

tan 30 =x/5√3

so x=5

as tan 30 is 1/√3
