Answer:
Area = 21.7 cm² (nearest tenth)
Step-by-step explanation:
A 30-60-90 triangle is a special right triangle. The measures of its sides have a special relationship in that they are in proportion:
shortest leg : longest leg : hypotenuse = 1 : √3 : 2
- The side opposite 30° is the shortest leg
- The side opposite 60° is the longest leg and is √3 times the length of the shorter leg.
- The side opposite 90° is the hypotenuse and is twice the length of the shorter leg.
So we can also write the ratio as
where
is the shortest side.
From inspection of the diagram, the shortest side is 5 cm
⇒ BC (height) = 5 × √3 = 5√3 cm
Now we have the height, we can calculate the area.
Area of a triangle = 1/2 x base x height
= 1/2 x 5 x 5√3
= 21.7 cm² (nearest tenth)

The perimeter is 16, according to my calculations.
<span>20 p/2 pounds = 20p/200p = 1/10</span>
The correct question is
The local currency it gives is a total of 275 Yuan. <span>If the yuan is worth 6.58 to a US$, what would the price to a US$ be if the yuan changed to 6.25
The </span><span>options are A)$2.21 B)$2.50 C)$13.31 D)$41.79 E)$44.00
we know that
</span><span>at the current exchange rate give (6.58)
</span>if 1 usd-----------------> 6.58 yuan
X usd------------------> 275 yuan
X=275/6.58------------> X=41.79 usd
at the current exchange rate give (6.25)
if 1 usd-----------------> 6.25 yuan
X usd------------------> 275 yuan
X=275/6.25------------> X=44 usd
so
the change in price in US$ would be [44-41.79]=US$2.21
the answer is the option
A)$2.21
