60 plus 20 * 10= 200 so 200+60= 260 milligrams
Answer:
15) diagonals are congruent in rectangles and squares; looks like a square
16) SW = 31
Step-by-step explanation:
since diagonals are congruent in rectangles then 'a+30' equals '2a+29'
a + 30 = 2a + 29
30 = a + 29
a = 1
SW = WU = TW = WV
Answer:
k = 2
Step-by-step explanation:
(-2,1) = (x,y) So you substitute -2 and 1 for x and y
1 = -(-2) - 1 1 = 1/2 × -2 + k
1/2 × -2 = -1 -1 + 2 = 1
k = 2 1 = 1/2 × -2 + 2

The angle of elevation of the sun from the ground to the top of a tree is 36 degrees
<h3><u>Solution:</u></h3>
Given that a tree that is 10 yards tall cast a shadow 14 yards long
To find: angle of elevation of sun
The figure is attached below
In the figure, AB represents the height of tree
BC represents the length of shadow cast by tree
We have to find angle of elevation θ
Now by using trignometric identity,
From the figure,
AB = Perpendicular = 10 yards
BC = Base = 14 yards
Thus the angle of elevation of sun from ground to top of tree is 36 degrees
