Answer:
true
Step-by-step explanation:
Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
UW = 45
a squared + b squared = c squared
- 6^2 + x^2 = 9^2
- 36 + x = 81
- (subtract 36 from both sides)
- x = 45
i'm pretty sure this is right and i hope it helps you!
Answer: x=-1
Step-by-step explanation:
- 3/4x+3-2x=-1/4+1/2x+5
- 3-5/4x=1/2x+19/4
- 7/4x=-7/4
- x=-1
To find the value of x, you must get it on its own:
3 - 2x = -5
+ 2x
3 = -5 + 2x
+5
8 = 2x
÷ 2
4 = x
Hope this helped!
