u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,

⇒ 
⇒ 
⇒ 
⇒ 
⇒ u = 10.4
Hence, u = 10.4 and v = 12.
Given radius=15 inches
Perimeter=circumference of circle
Circumference=2 pi r
=pi=22/7 or 3.14
=2*3.14*15=94.2
Rounded off=100
Your grammar is wrong. You aren't asking a question. I don't want to be mean but yeah you need to ask a real question.

Answer:
SA = 16 units^2
Step-by-step explanation:
B - base
H - height
SA - surface area
B = 2
H = 3
SA = (B × B) + 4((1/2)×(B × H))
SA = (2×2) + 4((1/2)×(2×3))
SA = <u>16 units^2</u>
