We know that An Isosceles Triangle has Two Equal Sides and Two Equal Angles Corresponding to those Two Equal Sides.
Given : WXY is an Isosceles Triangle :
From the Figure we can Notice that WY = XY
⇒ Angle (W) = Angle (X)
Given Angle (W) = (5x + 3)°
⇒ Angle (X) = (5x + 3)°
We know that Sum of Angles in a Triangle should be Equal to 180°
⇒ Angle (X) + Angle (Y) + Angle (W) = 180°
Given Angle (Y) = (11x - 15)°
⇒ (5x + 3)° + (11x - 15)° + (5x + 3)° = 180°
⇒ (21x - 9)° = 180°
⇒ 21x° = 189°
⇒ x° = 9°
⇒ Angle (Y) = (11x - 15)°
⇒ Angle (Y) = (11 × 9 - 15)° = (99 - 15)° = 84°
So the Measure of Angle (Y) = 84°
Answer:
<h2>£8.77</h2>
Step-by-step explanation:
100 - 16 = 84
84 / 100 = 0.84
10.44 x 0.84
=8.77
Answer:
It's C
Step-by-step explanation:
because 1.04 is closest to 1
For polynomials you need to remember that they have 2 things: terms and positive exponents.
1) is not polynomial because if you rewrite it the second term has a negative exponent ( -4x^-2)
2)is a polynomial
3) is a polynomial
4) is not a polynomial because if you convert the sqrt in a exponent you have a rational exponent (4x)^1/2
5) for standard form arrange the terms from the high to low degrees
X^11 -9x^7. +4x^5. -6
The degree is 11 the leading coefficient is 1
6) same idea as 5. The degree is 6 and leading coefficient is -2
7) degree 3 and has 3 terms
8) degree 2 and has 3 terms
Answer:
x=-12 and -3
Step-by-step explanation:
The quadratic formula is
.
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. We will substitute a=1, b=15 and c=36.
We will now simplify and solve.
x=-12 and x=-3
