4/5=0.8
0.35=7/20
3/8=0.375

You could have use a calculator for this but you’re welcome
Answer:
For the first one, it is 1150. For the second one, it is 2460.
Step-by-step explanation:
Think of 23 x 50 as (20 x 50) + (3 x 50).
20 x 50 is 1000. 3 x 50 is 150. 1000 + 150 is 1150.
Think of 30 x 82 as (30 x 80) + (30 x 2)
30 x 80 is 2400. 30 x 2 is 60. 2400+60 is 2460.
The correct answer is option B which is the set of values that could be the side lengths of a 30-60-90 triangle are (6,6√3, 12).
<h3>What is the right-angled triangle?</h3>
A triangle has three angles of 30-60 and 90 degrees in which the two sides are perpendicular to each other.
The three sides of the triangle will be calculated by applying the Pythagorean theorem:-
The sum of the square sides will be equal to the square of the third side.
For sides (6,6√3, 12)
12² = 6² + (6√3)²
144 = 36 + (36 x 3)
144 = 36 + 108
144 = 144
Therefore the correct answer is option B which is the set of values that could be the side lengths of a 30-60-90 triangle (6,6√3, 12).
