Abd is a right angled triangle so by pythagoras we know
![{g}^{2} = {11}^{2} + {13}^{2} \\ {g}^{2} = 290 \\ g = \sqrt{290} \: or \: g = 17.03cm](https://tex.z-dn.net/?f=%7Bg%7D%5E%7B2%7D%20%20%3D%20%20%7B11%7D%5E%7B2%7D%20%20%2B%20%20%7B13%7D%5E%7B2%7D%20%20%5C%5C%20%20%7Bg%7D%5E%7B2%7D%20%20%3D%20290%20%5C%5C%20g%20%3D%20%20%5Csqrt%7B290%7D%20%20%5C%3A%20or%20%5C%3A%20g%20%3D%2017.03cm)
and to calculate h we need to use the sine rule
![\frac{h}{ \sin(22) } = \frac{g}{ \sin(32) } \\ \frac{h}{ \sin(22) } = \frac{17.03}{ \sin(32) } \\ h = \frac{17.03}{ \sin(32) } \times \sin(22) \\ h = 12.04cm](https://tex.z-dn.net/?f=%20%5Cfrac%7Bh%7D%7B%20%5Csin%2822%29%20%7D%20%20%3D%20%20%5Cfrac%7Bg%7D%7B%20%5Csin%2832%29%20%7D%20%20%5C%5C%20%20%5Cfrac%7Bh%7D%7B%20%5Csin%2822%29%20%7D%20%20%3D%20%20%5Cfrac%7B17.03%7D%7B%20%5Csin%2832%29%20%7D%20%20%5C%5C%20h%20%3D%20%20%5Cfrac%7B17.03%7D%7B%20%5Csin%2832%29%20%7D%20%5Ctimes%20%20%5Csin%2822%29%20%20%20%5C%5C%20h%20%3D%2012.04cm)
i hope this helps
C=p+R x p
C=30.99 + .05 x 30.99
Order of operations states do the multiplication first
C=30.99 + 1.55
C=32.54
y-intercept is -6 (0,-6) and the x-intercept is -3 (-3,0)
Answer:
Step-by-step explanation:
(cos 4a*cos 2a+sin 4a*sin 2a)/sin 4a
=[cos (4a-2a)]/sin 4a
=(cos 2a)/sin 4a
=(cos 2a) /(2 sin 2a cos 2a)
=1/(2 sin 2a)
=1/2 csc 2a
