Answer: x=0,7
Step-by-step explanation:
Answer:
20°
Step-by-step explanation:
C70° vertically opposite... the alternate then vertically opposite again then 90° - 70° = 20°
8-4x-7=5x+30-2
combine like terms
1-4x=5x+28
-27=9x
divide both sides by nine
-3=x
it's very simple, 694-72= 622
so in order for you to check you answer you do the opposite
694-72 would equal 622
622+72 would equal 694
Answer:
x = 20 and y = 14.14213562 ( you can simplify it)
Step-by-step explanation
x = the opposite side divided by sin 45 ( the angle)
/ sin(45)
20
y = the opposite side divided by the adjacent side
/ tan(45)
14.14213562
14.14
