Given:

In a right angle triangle ABC, \angle B=90^\circ,x=8.7\ m, and \theta = 45^\circ

To find:

The value of AC.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Adjacent}{Hypotenuse}

\cos \theta =\dfrac{BC}{AC}

\cos (45^\circ) =\dfrac{8.7}{AC}

\dfrac{1}{\sqrt{2}}=\dfrac{8.7}{AC}

On cross multiplication, we get

AC=8.7\times \sqrt{2}

AC=12.30365799

AC\approx 12.304

Therefore, the measure of AC is 12.304 m.

A desk is on sale for $221.40, which is 73% less than the regular price.
olasank [31]
Since it is 73% less we need to do 100-73=27. this means that 27% of the original price is left. so we must devide 221.40 by 27% to find what 1% of original price was = 8.2 . so $8.2 is 1% of original price, therefore the original price is 8.2×100 = $820

Is -2/5 equal to 2/5
likoan [24]

Answer:

No

Step-by-step explanation:

-2/5 is not equal to 2/5 because it is negative and 2/5 is positive. This actually means that -2/5 is the opposite of 2/5.
