Area = Base*Height so Base = Area/Height = 39.2/5.6 = 7 units.
There will be 100 hand shakes because you would do 10x10 which is 100
Answer:
a) 5
b) 18 cm²
Step-by-step explanation:
a) Fie cel mai mic număr x, de aceea următorul număr consecutiv este x + 1.
Dacă suma a două numere naturale consecutive este egală cu 11:
x + (x + 1) = 11
x + x + 1 = 11
2x + 1 = 11
2x = 11 - 1
2x = 10
x = 10/2 = 5
Cel mai mic număr consecutiv este 5, Următorul număr consecutiv este 6 (5+1)
b) Un triunghi dreptunghic isoscel are o catetă egală cu 6cm,
de aceea baza este de 6 cm și înălțimea de 6 cm
aria triunghiului = 1/2 × baza ×înălţime = 0.5 × 6 × 6 = 18 cm²
You cannot draw a triangle with two right or two obtuse angles; the total measure of the angles in any triangle is 180 degrees.

x = 9</h2><h3 />
<u>We know:</u>
- we can add/subtract the same expression to both sides of the equation to get an equivalent equation;
- we can multiply/divide both sides of the equation by the same non-zero number to get the equivalent equation.
<u>Equivalent equations</u> are algebraic equations that have identical solutions.
We have the equation:
<h3>SOLUTION:</h3>
<em>multiply bot sides by 3</em>
<em />
<em>divide both sides by 7</em>
