Answer:
70.5°
Step-by-step explanation:
22² = (20)²+(18)² - 2(20)(18) cos X
484 = 400 + 324 - 720 cos X
-240 = -720 cosx
1/3 = cos X
= X
X = 70.52877937

3. 8² is 64cm
4.draw a square, make one side 6 feet then do 6² which is 36feet
5. do the same thing then write 10 inches on one side and 10² is 100 inches.
6. 7x3= 21 ft
7. 5x4= 20 in.
8. 2x8= 16 yd
