Answer:
La medida del tercer ángulo interno es 85°.
Step-by-step explanation:
Los triángulos son figuras geométricas planas que poseen tres lados en contacto entre sí en puntos comunes denominados vértices. A su vez, los triángulos poseen tres ángulos interiores. Estos tres ángulos interiores del triángulo suman 180°.
En este caso, en un triángulo, dos de sus ángulos internos miden 40º y 55º. Siendo θ el tercer ángulo interior, entonces:
θ + 40° + 55°= 180°
Resolviendo:
θ + 95°= 180°
θ= 180° - 95°
θ=85°

Hi there,
X x (-2) x 2 = 4 x (-2)
- x = - 2
Hence, X = 2
Hope this helps :)
Answer:
The missing number is 1000

Answer:
176
Step-by-step explanation:
In order to find these kinds of problems, you need to divide the given number by the percentage in its decimal form.
25% = 0.25
44/0.25 = 176
To check your work, simply take the answer and multiply it with the percentage.
176*0.25 = 44
