Answer:
(4+5)+(3+3) because you have eto break up the numbers
Answer:
15 feet
Step-by-step explanation:
The ladder is the hypotenuse of a right triangle, with the legs being 9 ft and 12 ft long (see the picture).
To solve for the length of the ladder, use the Pythagorean Theorem.
Answer:
<u>18 in²</u>
Step-by-step explanation:
<u>Given :-</u>
height (h) = 12 in.
base (b) = 3 in.
<u>To Find :-</u>
Area
<u>Formulas Required :-</u>
Area (triangle) = 1/2bh
<u>Solving :-</u>
= 1/2 x 3 x 12
= 6 x 3
<u>Solution :-</u>
<u>18 in²</u>
The triangle that is formed from by connecting the shadow, the tree and the endpoints of each is a right triangle. The two triangles formed (by the tree and its shadow, and by Rachel and her shadow) are similar. In similar triangles, the corresponding sides are proportional. Thus, to give the numerical answer to this item,
length of the tree/14 ft = 6 ft / 3.5 ft
length of the tree = 24 ft
Answer:
19 and 16
Step-by-step explanation:
Let x and y be the two numbers
x+y = 35
x-y =3
Add the two equations together
x+y = 35
x-y =3
---------------
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
Solve for y
x-y = 3
19-y = 3
Subtract 19 from each side
19-19 -y = 3-19
-y = -16
y =16
