Exterior Angle Property
Step-by-step explanation:
Interior Angle :
The angle formed with in the closed boundary of the triangle is called an interior angle.
In the given figure, α , β and γ are interior angles.
Exterior Angles:
The angle formed outside the closed boundary of the triangle is called an exterior angle.
In the given figure, γ' is an exterior angles.
Sum of the measures of the two non-adjacent interior angles is EQUAL to measure of an exterior angle of a triangle.
⇒ α + β = γ'
This property is known as " Exterior Angle Property"
Also, here angles γ and γ' are making a linear pair.
γ + γ' = 180°
Answer:
x= -12
Step-by-step explanation:
move variable to left and change its sign
= 4x - 20 = -68
move constant to the right and change its sign
= 4x = -68 + 20
calucate the sum
= 4x = -48
divide both sides of the equation by 4
x= -12
The expression is equivalent to r^(m-n)
<span>Equation at the end of step 1 :</span><span> (((x3)•y)-(((3x2•y6)•x)•y))-6y = 0
</span><span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> -3x3y7 + x3y - 6y</span> = <span> -y • (3x3y6 - x3 + 6)</span>
Trying to factor a multi variable polynomial :
<span> 3.2 </span> Factoring <span> 3x3y6 - x3 + 6</span>
Try to factor this multi-variable trinomial using trial and error<span>
</span>Factorization fails
<span>Equation at the end of step 3 :</span><span> -y • (3x3y6 - x3 + 6) = 0
</span><span>Step 4 :</span>Theory - Roots of a product :
<span> 4.1 </span> A product of several terms equals zero.<span>
</span>When a product of two or more terms equals zero, then at least one of the terms must be zero.<span>
</span>We shall now solve each term = 0 separately<span>
</span>In other words, we are going to solve as many equations as there are terms in the product<span>
</span>Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
<span> 4.2 </span> Solve : -y = 0<span>
</span>Multiply both sides of the equation by (-1) : y = 0
Multiply 51% times 128 and u get 128
