Find BC. Round to the nearest tenth
SSSSS [86.1K]
<span>Using LAW OF SINES Round to the nearest tenth. 
Find BC: triangle is laying on it's side with the point to the right point(A).

B to C= 61 degrees
C to A= 23 cm
A to B= 12 degrees
--------------------
If I interpret this correctly:
Angle A = 61º

Angle C = 12º
--> B = 103º
-------------
Side b = 23 cm
--------------
BC is side a, opposite angle A
--------------
23/sin(103) = a/sin(61)
a = 23*sin(61)/sin(103)
a =~ 20.6 cm 

Hope this helped :)</span>

Georgia [21]

Answer:

(1)55.5 feet

(2)7.5 feet

Step-by-step explanation:

<u>Question 1</u>

The diagram is attached below.

Using Trigonometric ratio

\tan 48^\circ = \dfrac{h}{50} \\h=50 \times \tan 48^\circ\\h=55.5$ feet (to the nearest tenth)

The height of the house is 55.5 feet to the nearest tenth.

<u>Question 2</u>

In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.

Using Trigonometric ratio

\tan 15^\circ = \dfrac{2}{x} \\x \tan 15^\circ=2\\x=2 \div \tan 15^\circ\\x=7.5 $ feet (to the nearest tenth)

The distance the bird must fly to be directly above the fish is 7.5 feet.

what is the relationship between 5.34 x 10^5 and 5.34 x 10^-2 is it greater or lesser than? for 5.34 x 10^5? will give brainlies
Romashka-Z-Leto [24]

the relationship between 5.34 x 10^5 and  5.34 x 10^-2

5.34 x 10^5 = 5.34*100000= 534000

5.34 * 10^-2  , for exponent -2 we move the decimal point 2 places to the left

5.34 x 10^-2= 0.0534

Now we compare 534000  and 0.0534

0.0534 is 10,000,000 times less than 534000

Or we can say  534000 is 10,000,000 times greater than 0.0534

5.34 x 10^5 is 10,000,000 times greater than 5.34 x 10^-2
