Answer:

64.98\°

Step-by-step explanation:

we know that

In the right triangle of the figure

tan(A)=\frac{BC}{AB} ---> opposite side to angle A divided by the adjacent side to angle A

substitute the values

tan(A)=\frac{15}{7}

A=arctan(\frac{15}{7})=64.98\°

Explain which is faster: 10 centimeters/5 seconds or 10 centimeters/20 seconds.
Diano4ka-milaya [45]

Answer:

10 centimetre / 5 seconds

Step-by-step explanation:

10 cm / 5 sec means that you are travelling 10 cm every 5 seconds. Or 2 cm every 1 seconds. ( Divide by 5).

10 cm / 20 seconds means that you are travelling 10 cm every 20 seconds. Or  0.5 cm ever 1 second. (Divide by 20)

2. Find the number of distinct triangles with c=11,b=7,B=18 a.0 b.1 c.2 d. cannot be determined
jok3333 [9.3K]
Answer: Choice C) 2

----------------------------------------------

Explanation:

Using the law of sines, we get
sin(B)/b = sin(C)/c
sin(18)/7 = sin(C)/11
0.0441452849107 = sin(C)/11
11*0.0441452849107 = sin(C)
0.4855981340177 = sin(C)
sin(C) = 0.4855981340177
C = arcsin(0.4855981340177) or C = 180-arcsin(0.4855981340177)
C = 29.0516679549861 or C = 150.948332045013
There are two possibilities for angle C because of something like sin(30) = sin(150) = 1/2 = 0.5

Those approximate values of C round to
C = 29.05 and C = 150.95

If C = 29.05, then angle A is
A = 180-B-C
A = 180-18-29.05
A = 132.95
Making this triangle possible since angle A is a positive number

If C = 150.95, then angle A is 
A = 180-B-C
A = 180-18-150.95
A = 11.05
making this triangle possible since angle A is a positive number

There are two distinct triangles that can be formed. 
One triangle is with the angles: A = 132.95, B = 18, C = 29.05
The other triangle is with the angles: A = 11.05, B = 18, C = 150.95
The decimal values are approximate
