The first step to solve this problem is to find the area of
the rectangular piece of fabric.
A of triangle = bh/2
A = (14 cm) (6 cm) /2
A = 84 cm^2 / 2
A = 42 cm
And since there are 31 pieces of the fabric, the total area
of all the pieces of fabric is:
31 pieces of fabric x 42 square centimeters per piece =
1,302 square centimeters
To computer how many congruent triangular patches can be
cut, you have to divide the total area of the fabric pieces with the area of
the congruent triangle:
1,302 square centimeters / 21 square centimeters = 62
Therefore, Leia can cut 62 patches.
Combine the like terms:
3 - 12t + 8t = 3 - 4t
simplified answer is
-4t + 3
Answer:
The value of Tan (a + b) is 
.
Step-by-step explanation:
Given as :
Tan b = 
Sin a = 
∵Sin Ф = 
So, =
Now, Base² = Hypotenuse² - Perpendicular²
Or, Base² = 13² - 12²
Or, Base² = 169 - 144
Or, Base² = 25
∴ Base = 
= 5
And Tan Ф = 
Or, Tan a = 
Now, Tan (a + b) = 
Or, Tan (a + b) = 
or, Tan (a + b) = 
or, Tan (a + b) =
Or, Tan (a + b) =
Hence The value of Tan (a + b) is . Answer
Answer:
Step-by-step explanation:
Answer:
6 5/6
Step-by-step explanation:
because two sides are the same on each side so 2 2/3×2 and 3/4×2 then add those two answers which are 5 1/3 and 1 1/2 and adding those would be 6 5/6
