Answer:
74°
Step-by-step explanation:
From the attached figure, translation only affects the length of the sides of the triangle :
From the figure :
We are given ;
A = 80° ; C = 26° ; B =?
Sum of angles in a triangle :
A + B + C = 180°
80° + B + 26° = 180°
106° + B = 180°
B = 180 - 106
B = 74°
Answer:
9074
Step-by-step explanation:
<h3>The height of the ball after 2 seconds is 36 units </h3>
<em><u>Solution:</u></em>
The pathway of the ball from the machine can be represented by the equation:

To find: height of the ball after 2 seconds
<em><u>Substitute t = 2 in above equation</u></em>

Thus the height of the ball after 2 seconds is 36 units
Answer:
b
Block B has the greatest density.
Step-by-step explanation:
density = mass/volume
volume = length × width × height
All blacks have the dimensions 7 cm by 3 cm by 1 cm, so the 3 volumes are equal.
Since density = mass/volume, and the volumes are equal, the block with the highest mass has the highest density.
Since all the masses are different, all densities are different.
Answer: Block B
