Answer:
7.6yd
Step-by-step explanation:
You first have to use sin, because you are dealing with opposite and hypotenuse.
Sin(39)×12
Shows that the sides is 7.55 yards
Answer:
20
Step-by-step explanation:
An angle bisector cuts an angle into two equal parts. So m∠ACE = m∠ECB.
m∠ACE = m∠ECB
2x − 15 = x + 5
x = 20
-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19
The equation:
-8x - 46 = -6x - 8
The solution:
x = -19
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
