Answer:
6
Step-by-step explanation:
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6
Answer:
C, 108 ft²
Step-by-step explanation:
To solve, we need to find the area of each of the shapes and then add them together.
The top rectangle's area: 8 * 3 = 24
The left triangle: 3 * 4 * 0.5 = 6
The middle rectangle: 8 * 4 = 32
The right triangle: 4 * 3 * 0.5 = 6
The bottom rectangle: 5 * 8 = 40
Add them all together.
24 + 6 + 32 + 6 + 40 = 108 ft²
Thus, the answer is C, 108 ft²
Well, these are quite simple really, especially 1,2,3 and 4. If you read the questions carefully, you can understand it well. You don’t need to know the answer, you just need to understand
70.8 fish tanks. Because you have to divide 354 by 5.
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
