Answer:
c) (i) 33
Step-by-step explanation:
Answer:
y = 47
Step-by-step explanation:
All of the angles in a triangle must add up to 180. The angle marked 3y can help us find the missing angle of the triangle: 180-3y
Then you can make an equation to help solve for y:
50 + (2y-3) + (180-3y) = 180
Combine like terms:
227-y=180
y = 47
Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
![85 = 4z + 3z + 3 + z + 2](https://tex.z-dn.net/?f=%2085%20%3D%204z%20%2B%203z%20%2B%203%20%2B%20z%20%2B%202%20)
Collect like terms
![85 = 8z + 5](https://tex.z-dn.net/?f=%2085%20%3D%208z%20%2B%205%20)
Subtract 5 from both sides
![85 - 5 = 8z](https://tex.z-dn.net/?f=%2085%20-%205%20%3D%208z%20)
![80 = 8z](https://tex.z-dn.net/?f=%2080%20%3D%208z%20)
Divide both sides by 8
![10 = z](https://tex.z-dn.net/?f=%2010%20%3D%20z%20)
![z = 10](https://tex.z-dn.net/?f=%20z%20%3D%2010%20)
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units
