Answer: he moves 50 steps
Step-by-step explanation:
He went 20 on his first because 1/5 of 100 then it says 1/4 of his first turn which is 5 and then 1.25=1 1/4 of his first turn which is 25 so 20+5+25= 50
3 + 5x = 20 + 7x
First subtract 20 to both sides
-17 + 5x = 7x
Next subtract 5x to both sides (we are trying to get x all in one side)
-17 = 2x
Divide 2 to isolate the x
-17/2 = x or -8.5 = x
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
