The irrational numbers among these given are:

The remaining numbers are all rational.
<h3>What are rational and irrational numbers?</h3>
- Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
- Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.
The irrational numbers in this problem are:
- Square root of 83, as it is a non-exact root.
- 24π, as π is a non-terminating decimal.
- 90.790170, which is a non-terminating decimal.
- Square root of 109, as it is a non-exact root.

All Triangles are equilateral ( each side = 4)
Area of a Triangle is (B x H)/2. B being the base ( 4) & H the altitude.
WE know that altitude in an equilateral triangle, H = ( side x√3)/2
So H= (4√3)/2 = 2√3
The area of one triangle = (4 x 2√3)/2 = 4√3
And for the 3 triangles the lateral area = (4√3) x 3 = 12√3
Take and do 8/9 - 1/5 which gives u 40/9which equals 4 4/9.
Answer:
t=3
Step-by-step explanation:
4-t=3t-3-5
4-t=3t-8
+1
4=4t-8
