Answer:
b = 
Step-by-step explanation:
Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.
Thus, to determine the value of b;
Sin θ = 
Sin b = 
=
= 0.38462
⇒ b = 
0.38462
= 22.6202
b =
The measure of angle E (= b) is .

20% of 120 is 20.
120-20 + 100
Answer:
x = 9
Perimeter = 74
Area = 342
Step-by-step explanation:
First, find x. to do so, set your formula up as
18 = 8x - 54
18 + 54 = 8x
72 = 8x
72/8 = x
9 = x
Now that you have x, find your missing side
2x + 1 = y, x
2 * 9 + = y
19 = y
Your perimeter is P = 2(l+W)
P = 2(18 * 19)
P = 74
Your area is A = wl
A = 19 * 18
A = 342
Answer:
● 
Step-by-step explanation:
According to the Definition of Rational Exponents [part I], you can rewrite radicals as exponents:
![\displaystyle a^{\frac{m}{n}} = \sqrt[n]{a}^m \\ \\ \sqrt{y^2} = y, where\:any\:invisible\:exponent\:is\:ALWAYS\:1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%7D%5Em%20%5C%5C%20%5C%5C%20%5Csqrt%7By%5E2%7D%20%3D%20y%2C%20where%5C%3Aany%5C%3Ainvisible%5C%3Aexponent%5C%3Ais%5C%3AALWAYS%5C%3A1)
