Answer:
1.53
Step-by-step explanation:
because 21 minus 19.47= 1.53
10,000 x .10 = $1000
22500-10000=12500 x .12 = $1500
$1000 + $1500 = $2500
Use the concept of Lagrange multipliers.
Answer:
38.60mm
Step-by-step explanation:
Step one:
Given data
We are given that the dimension of the triangles are length 23 mm and 31 mm
Let us assume that the triangle is a right angle triangle
Step two:
Applying the Pythagoras theorem we can find the third as

square both sides
z= √ 1490
z= 38.60mm
Hence a possible dimension of the third side is 38.60mm
9+12>18
12+18>9
9+18>12
So, yes. A triangle can be formed by the given angles.
