What is the value of X in the triangle attached?

Juliette [100K]

Answer:

X = 22°

Step-by-step explanation:

Accordng to Exterior Angle Sum Property , measure of an exterior angle is equal to the sum of the 2 interior opposite angles.

So,

$(2x) + (103 - x) = 6x - 7$

$= > x + 103 = 6x - 7$

$= > 6x - x = 103 + 7$

$= > 5x = 110$

$= > x = \frac{110}{5} = 22$

In the equation (x^2+y)^5, what is the coefficient of the term x^4y^3? what is the coefficient of the same term in the expansion

lys-0071 [83]

$\displaystyle
(x+y)^n=\sum_{k=0}^n\binom{n}{k}x^{n-k}y^k$

<em>-------------------------------------------------------------</em>

$\displaystyle
(x^2+y)^n=\sum_{k=0}^n\binom{n}{k}x^{2n-2k}y^k\\
n=5\\
k=3\\\\\binom{5}{3}=\dfrac{5!}{3!2!}=\dfrac{4\cdor5}{2}=10$

<u>It's 10.</u>

----------------------------------------------------

$\displaystyle
(3x^2+y)^n=\sum_{k=0}^n\binom{n}{k}(3x)^{2n-2k}y^k=\sum_{k=0}^n\binom{n}{k}\cdot 3^{2n-2k}\cdot x^{2n-2k}y^k\\\\
n=5\\
k=4\\\\
\binom{5}{3}\cdot3^{2\cdot5-2\cdot4}=10\cdot3^{2}=10\cdot9=90$

<u>It's 90</u>

What is the value of Y? WILL GIVE BRAINLIEST

Mrrafil [7]

Answer

54 degrees

Step-by-step explanation:

Using angle sum property(angles in a triangle add up to 180),

y+y+72=180

2y+72=180

2y=180-72

2y=108

y=108/2

y=54 degrees

pls mark brainliest
