Answer:
11. x=10, y=14.1421356237
12. x=12.124355653, y=14
Step-by-step explanation:
11. Use tan and pythagorus
tanA=opposite/adjacent
tan45=x/10
10(1)=x
x=10
a²=b²+c²
y²=x²+10²
y²=10²+10²
y²=100+100
y=√200=14.1421356237
12. Use tan and pythagorus
tanA=opposite/adjacent
tan30=7/x
0.57735026919x=7
x=7/0.57735026919
x=12.124355653
a²=b²+c²
y²=x²+7²
y²=12.124355653²+7²
y²=147+49
y=√196=14
Well, 7*3= 21 so all you have to do is add the zeros to get: 210,000
:)
Hope this helped!
<span>There is not a property of "1" for addition, but the identity property in this case uses "0" instead. If a number is increased by 1, the value will necessary be increased or decreased by the amount added or subtracted. However, if the number either adds or subtracts zero, then value will be left unchanged. Examples: 3+1 = 4, but 3+0 = 3,</span>

Answer:
888.89 km
Step-by-step explanation:
Write the given question as an equation and solve.
80 km = 0.09 × (what distance)
(80 km)/0.09 = what distance . . . . . divide by the coefficient of the variable
888.89 km ≈ what distance
80 km is 9% of 888.89 km
