Answer:
y=70°
z= 60°
w= 70°
Step-by-step explanation:
Since the two triangles are similar, we know that all of the corresponding angles must be the same. On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°. This means that the same angle is formed at Z, which is in the same location on the triangle to the right. From there, we can find the missing angle, W, from the difference of 180°.
180°-50°-60°=70°.
The same way we found Z, we can also find Y, since it has to be the same as W.
Answer:
Mean = 4
Step-by-step explanation:

The product will have 9 digits after decimals . This is because the number of decimal points are added in multiplication.
For eg. 2.5×2.5=6.25 , 0.5×0.5=0.25 .

Explanation:
When it comes to negative and positive numbers you must be careful.
For a positive number, the bigger it is is the greater it'll get
For negative numbers, as the numbers continue to increase the less the value will become.
