Answer:
so length of sides is 6 .2 m ( other side will also be 6.2 m)
base = 3.2 cm
Step-by-step explanation:
solution
let the length of sides of isosceles triangle is = x
as two sides of of isosceles triangle are equal
let the length of the side be x
so length of side = x
base = x -3 ( as it is 3 m smaller in length )
according to formula of perimeter of isosceles triangle
perimeter = 2 (side) + Base
adding the values
15.6 = 2 (x) + x-3
15.6 = 2x +x -3
15.6 = 3x-3
15.6 = 3( x-1) taking 3 common
dividing both sides by 3
15.6/3 = 3(x-1)/3
5.2 =x-1
or x -1 = 5.2
adding 1 from both sides
x-1 +1 = 5.2 +1
x = 6.2
so length of sides is 6 .2 m ( other side will also be 6.2 m)
base = x-3 = 6.2-3 = 3.2 m

QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12
Answer:
24.58%
Step-by-step explanation:
Given that,
Initial cost = $240
Final cost = $299
We need to find the percentage in his profit of the cost price.
Profit = Final cost - Initial cost
= $299 - $240
= $59
Percentage,
So, the required percentage is equal to 24.58%.
Answer:
c = 60.65 cm
Step-by-step explanation:
Given that,
The two sides of a triangle are 33 cm and 37 cm.
The angle between these two sides is 120°.
We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,
a = 33 cm, b = 37 cm and C is 120°
So,
So, the length of the third side of the triangle is 60.65 cm.
