Step-by-step explanation:
Since , internal sum of angle of triangle is 180°
So,
66 + x +49 + x+83 = 180
or, 198 + 2x = 180
or, 2x = 180 -198
or, 2x = -18
hence, x = - 9
Now angle A = x + 49
= (-9) + 49
= 40
<u>Hence </u><u>measure</u><u> </u><u>of </u><u>angle </u><u>A </u><u>is </u><u>4</u><u>0</u><u>°</u><u>.</u>
Answer:
Step-by-step explanation:
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³

Answer:
In x-axis:
, In y-axis: 
Step-by-step explanation:
The rule of the reflection of a point across the x-axis is as shown:
The reflection of the point
across the x-axis is given by
.
The point given to us is
, when reflected across the x-axis we get:

Now, when a point
is reflected across the y-axis we get the point
.
So when the point
is reflected across the y-axis we get:
.
