1. AB
AB is adjacent to the 50 deg angle.
You also know the hypotenuse, so use CAH.
![\cos 50^\circ = \dfrac{AB}{9}](https://tex.z-dn.net/?f=%20%5Ccos%2050%5E%5Ccirc%20%3D%20%5Cdfrac%7BAB%7D%7B9%7D%20)
![AB = 9 \cos 50^\circ = 5.8](https://tex.z-dn.net/?f=%20AB%20%3D%209%20%5Ccos%2050%5E%5Ccirc%20%3D%205.8%20)
2. BC
BC is opposite the 50 deg angle.
You also know the hypotenuse, so use SOH.
![\sin 50^\circ = \dfrac{BC}{9}](https://tex.z-dn.net/?f=%20%5Csin%2050%5E%5Ccirc%20%3D%20%5Cdfrac%7BBC%7D%7B9%7D%20)
![BC = 9 \sin 50^\circ = 6.9](https://tex.z-dn.net/?f=%20BC%20%3D%209%20%5Csin%2050%5E%5Ccirc%20%3D%206.9%20)
3. <C
<C is complementary to the 50 deg angle.
m<C + 50 = 90
m<C = 40
Identifying the part and the whole helps you write a percent proportion because the whole goes in the denominator of a fractions, and part is the numerator, then you divide the fraction giving you the percent.
The answer is 64
12/1.5 = 8
8 x 8 = 64
No.
4 meters is 400 centimeters, so is smaller than 450 centimeters.
