I got you covered. There are two ways to write Θ: degrees [°] and radians [expressed as "π"]. So, in this case cos π/3 = ½ [radian measure], or cos 60° = ½ [degree measure]. The reason being is because to convert from degrees to radians, use this formula: [degree measure] π/180; if you were to convert from radians to degrees, you'd do this vice versa: [radian measure] 180/π. So basically, the unit you're trying to convert to, is the one that goes in your numerator.
Answer:
A
Step-by-step explanation:
Its a simple equation.
Answer:
Roughly 70.29 degrees
Step-by-step explanation:
Equation:
(2x+27)+(2x-11)+3x = 180
7x + 16 = 180
7x = 164
x ~ 23.43
Angle C:
3x
3(23.43)
70.29
Since these are similar triangles you can use any two corresponding sides to figure out the scale factor.
Use the bottom side. Going from the first triangle to the second the scale factor is:
15/9 = 5/3
It's C.152.068
That's the right answer alright! Not because I copied or anything like that but because if you do 56.02-4.6 on a calculator and then add 100.648 you will get the right answer That's how I got my answer :P
