Based on the angles, we know this is a 45-45-90 triangle.

In this type of triangle, x and y will be equal. The formula for the sides is x * rad 2 = 8 .

8/ rad 2 = 5.66

Both X and Y are 5.66 units.

Answer:

x = 6.81 and y = 4.20

Step-by-step explanation:

by using SOHCAHTOA

hypotenus = 8

adjacent = x

opposite = y

sin45° = y/8

y = 8sin45°

y = 6.66

cos45° = x/8

x = 8cos45°

x = 5.66

Solve for y, given that b=22(Round your answer to 1 decimal place, if necessary.)
timurjin [86]

Answer:

37.7

Step-by-step explanation:

First, we have to divde 22/7 to find the scale factor. I chose 22 and 7 because those two sides are ocngruent. We get 3.14. We then have to multiply 12 by 3.14 beacuse that is the side that is congruent with the side y. When you multiply you should get 37.68. Since we have to round we get 37.7.

32 is 90% of what number?
spayn [35]

Answer:

\large\boxed{32\ is\ 90\%\ of\ 35\dfrac{5}{9}}

Step-by-step explanation:

<h3>METHOD 1:</h3>

\begin{array}{ccc}32&-&90\%\\\\x&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\90x=3200\qquad\text{divide both sides by 90}\\\\x=\dfrac{3200}{90}\\\\x=\dfrac{320}{9}\\\\x=35\dfrac{5}{9}

<h3>METHOD 2:</h3>

\begin{array}{cccc}32&-&90\%&\text{divide both sides by 9}\\\\\dfrac{32}{9}&-&10\%\end{array}\\\\\\90\%+10\%=100\%\to32+\dfrac{32}{9}=32+3\dfrac{5}{9}=35\dfrac{5}{9}
