Why did the bike fall over?
Answer:
84 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 5+9) * 12
A = 1/2 (14) * 12
A =84
Answer:
The length of the necklace is 12.20 foot
Step-by-step explanation:
Given as :
The height of the ice cream cone to the ground = h = 10 foot
The angle make by the necklace of the ice cream cone = 55°
Let The length of the necklace = L foot
<u>Now, from figure </u>
Height = BC = h foot
The length of the necklace = L = AC
So, Sin angle =
Or, Sin 55° =
Or, 0.8191 =
Or, 0.8191 =
Or, L =
∴ L = 12.20 foot
So, The length of necklace = L = 12.20 foot
Hence The length of the necklace is 12.20 foot Answer
2x = 2√17 and 3x = 3√17
Step-by-step explanation:
- Step 1: Given length of the rectangle is 3x and breadth is 2x. Area is 102 m². Area of the rectangle = length × breadth
102 = 2x × 3x = 6x²
x² = 102/6 = 17
x = √17
Length 2x = 2√17 and Breadth = 3x = 3√17
