Using sin law;

sin A/ a = sinB/ b

where A = C or 90 degrees; a = 21
B = ? , b = 8

solving for b;
sin(90) / 21 = sin(B) / 8 ; B = 22.39 degrees

Total angle of triangle = 180

180 - 90 - 22.39 = x
x = 67.607 degrees

REY [17]
Hello,
We see that there is the ratio
2:3:4, which let us to conclude the ratio between the shortest and longest side is 2:4 or 1:2, so the longest side is two times bigger than the smallest.
To find the longest side:
12×2=24 cm. As a result, the length of the longest side is 24 cm. Hope it help!

Simplify 425xy⁴/25xy²
beks73 [17]

We have the expression

\frac{425xy^4}{25xy^2}

We can already simplify x because it's both on the numerator and denominator

\frac{425y^4}{25y^2}

Now we can simplify 425/25 = 17

\frac{17y^4}{y^2}

Remember that

\frac{a^n}{a^m}=a^{n-m}

Then

17y^{4-2}=17y^2

The final result is

17y^2

AfilCa [17]
Hello! I can help you!
So, when you look at the problem, 75h can not be it. The answer is definitely 0.09, because that mean stuff you'd have to pay 9% tax and that usually the amount of tax you may pay on some items. The part of the expression that represents tax is 0.09.
