Answer:
x=14.42192
Step-by-step explanation:
Angle A = 180 - 86 =94
The sum of the angles of a triangle is 180
sin A sin 46
------- = -----------
20 x
sin 94 * x = 20 sin 46
x = 20 sin 46 / sin 94
x=14.42192

Answer:
The answer to your question is 7 large and 16 small
Step-by-step explanation:
Data
cost large frame = $13
cost small frame = $5
total number of frames = 23
total cost = $171
large frame = l
small frame = s
Process
- Write equations that help to solve the problem
l + s = 23 Equation l
13l + 5s = 171 Equation ll
-Multiply equation l by -5
-5l - 5s = -115
13l + 5s = 171
8l + 0 = 56
8l = 56
l = 56/8
l = 7
-Find s
7 + s = 23
s = 23 - 7
s = 16
-Conclusion
She bought 7 large frames and 16 small frames.
Answer:

Step-by-step explanation:
True
Answer:
x = 175
Step-by-step explanation:
