The area of a triangle can be found by multiplying the base and the height, and dividing the product by 2.
So, 10*8=80
80/2=40 in^2
Then, the triangle on the left:
10*12=120
120/2=60 in^2
Add up the areas
40 in^2+60 in^2=100 in^2
Here you would want to use the sine function, since it’s making a triangle with the ground, and length of the string, the height to the kite. This can be found by 65sin(70°) which is ≈ 61.08 meters
The error Soro makes while solving inequality is that "Soro should have reversed the inequality symbol when using the division property of inequality".
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The inequality is given as 50-2.5x≥20, now solving the inequality,
Divide both sides of the inequality by -2.5x, therefore, reverse the inequality symbol when using the division property of inequality.
Hence, the error Soro makes when writing or solving inequality 50-2.5x≥20, is that "Soro should have reversed the inequality symbol when using the division property of inequality".
