Answer: 7a
Step-by-step explanation: Since they are like terms, you can just add or subtract them.
4a - 5a = -1a
2a + 6a = 8a
-1a + 8a = 7a
Answer:
72
Step-by-step explanation:
6x+6x+8x=180 (∠ sum of Δ)
20x=180
x=9
∠ABC=8(9)
=72
Answer: Calculate the volume of each individual figure and add them.
Step-by-step explanation:
1. A composite figure is formed by two or more figures.
2. Then, to calculate the volume of the composite figure you must calculate the volume of each individual figure and then you must add all the volumes obtained.
3. For example, if a composite figure has a cylinder and a cone, the volume of the composite figure will be the sum of the volume of cylinder and the volume of the cone:

Answer:
a = 7
Step-by-step explanation:
This is a special trig triangles. Special trig triangles are identified by their angle measures and their sides have a unique relationship. This is a 30 - 60 - 90 triangle which has sides 1 - √3 - 2 or multiples of this. This means all 30 - 60 - 90 triangles have side lengths with the pattern 1 - √3 - 2. Here the triangle has a - 7√√3 - 14. The value of a is 7 since 7*√3 = 7√3 and 2*7 = 14.
