Answer:
To find h the altitude we use sine
sin ∅ = opposite / hypotenuse
From the question
AC is the hypotenuse
h is the opposite
sin 29 = h / 23
h = 23 sin 29
h = 11.1506
h = 11.00mm to the nearest hundredth
Hope this helps you
Answer:
2(x-9) = 2
Step-by-step explanation:
Difference indicates subtraction:
The difference of a number and
9
is
(
x
−
9
)
Twice the difference means
2
(
x
−
9
)
We know that the answer to this is
2
, so as an equation:
2
(
x
−
9
)
=
2
If you solve it we would have:
x
−
9
=
1
←
÷
2
x
=
1
+
9
x
=
10
The difference between
10
and
9
is
1
and twice
1
is
2
.
The number is correct.
Note that written as:
The difference of twice a number and
9
would have a different expression. This would be
2
x
−
9
