You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3

So your answer is x = 3, I hope this helps!

zheka24 [161]

Answer:

5ab + 8 - 1a^2.

Step-by-step explanation:

Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2

solniwko [45]

Answer:

Bola is 8 years old.

Step-by-step explanation:

Let Bola's age be x

Dada's age be y

Ayo's age be z

If the sum of ages of Bola, Dada and Ayo is 32 years, then;

x + y + z = 32

If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z

Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:

T = 400 + 400 + 800

T = N1600

Next is to get the age of Bola

$\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share$

Substitute the required variables and values into the formula;

$\frac{x}{32}*1600= 400\\50x=400\\x=\frac{400}{50}\\x=8$

This shows that Bola is 8 years old
