Answer:

The measure of the fourth angle = 137.1°

Step-by-step explanation:

Let x = the measure of the fourth angle

Sum of all 4 interior angles in a quadrilateral equal 360°

so

x + 23.5° + 99° + 100.4° = 360°

x + 222.9° = 360°

              x = 360° - 222.9°

              x = 137.1°

stepladder [879]

Answer:

1 1/2 kg de queso

De la pregunta anterior, sabemos que:

1 queso = 1/4 kg

6 quesos = x kg

Multiplicar cruzada

1 queso × x kg = 6 quesos × 1/4 kg

x kg = 6 quesos × 1/4 kg / 1 queso

x kg = 3/2 kg

x kg = 1 1/2 kg de queso
