Answer:
17.6 feet
Step-by-step explanation:
If Diana walks forward and her angle looking to the top of the building changes to 40°, how much closer is she to the building? Round the answer to the nearest tenth of a foot.
Let x be the distance between the building and Diana,
Tan theta = opposite / adjacent side
then tan 37 = 130/x
Let y be distance between the building and Diana after moving forward,
now find the distance by subtracting to find how much closer she is to the building
Answer:
Hi!
The name of the equation is the Pythagorean Theorem.
A and B both are the lengths of the legs of a right triangle, while C is the length of the hypotenuse.
Hope I helped! Have a good day :)
Answer:
132 cm cubed
Step-by-step explanation:
so if = 3
cylinder 1 = 3 x 2 x 2 x 7 = 84 cm cubed
cylinder 2 - 3 x 4 x 4 x 1 = 48 cm cubed
all together = 84 + 48 = 132 cm cubed
area of this object = 132 cm cubed
We have that since the chords are equal, the arcs are equal too. Hence AB=RS. We also have that AB=AR+RB and RS=RB+BS. By equating these two, we have that AR=BS. Hence BS=55 degrees. Substituting back, since we know RB and BS, we get: RS=55+66=121 degrees
