Hello from MrBillDoesMath!
Answer:
B = 67.4 degrees (approximately)
Discussion:
From plane trigonometry
sin(B) = side opposite angle B \ hypotenuse
= 12/13
Use a calculator (take the inverse sine of 12/13) gives
B = 67.4
Thank you,
MrB
Answer:
Percent increase = 25%
Step-by-step explanation:
Given that:
Old price of shoes = $65
New price of shoes = $81
Difference = 81 - 65
Difference = 16
Percent increase =
Percent increase =
Percent increase = 0.246 * 100
Percent increase = 24.6%
Rounding off to nearest whole number
Increase = 25%
Hence,
Percent increase = 25%

Answer:
The answer is A
Step-by-step explanation:
I'm good at factoring lol
I would convert to degrees first seems to make it easier.

= -468
by adding 360 twice we get the coterminal angle 252
252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72
If necessary convert back to radians...
