All angles on a triangle add up to 180. If it's a right triangle it would be set up like this: 90+3x-4=6x-5=180. You would subtract 90 from 180 and get 90 left. 3x-4+6x-5=90. Then you would add 5 and 4 to 90.....3x+6x=99. Then you add 3x and 6x then you would be left with 9x=99. Divide 99 by 9 and you get x=11.
Answer:
⅘ or 0.8
Step-by-step explanation:
Hypotenuse² = 3² + 4²
Hypotenuse = 5
Sin(θ) = 4/5
35 is the 20% so you multiply 35x5=175. 175 is the whole thing so you minus 175-35=140 which is the remaining money so half of that is 70
Answer:
Step-by-step explanation:
log (x+3)=log8-log2
log(x+3)=log(8/2)=log4
x+3=4
x=4-3=1
