Answer:
The generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
Step-by-step explanation:
We are given the following from what she knows
m∠3=2⋅m∠1... 1
m∠2=2⋅m∠4 ... 2
m∠2+m∠3=360 ... 3
From what is given, we can substitute equation 1 and 2 into equation 3 as shown:
From 3:
m∠2+m∠3=360
Substituting 1 and 2 we will have:
2⋅m∠4 + 2⋅m∠1 = 360
Factor out 2 from the left hand side of the equation
2(m∠4+m∠1) = 360
Divide both sides by 2
2(m∠4+m∠1)/2 = 360/2
m∠4+m∠1 = 180°
Since the sum of two supplementary angles is 180°, hence the generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
The fraction of the poster does Dwayne use for his friends from school is 5/12.
<h3>What is the fraction of the poster that Dwayne uses for his friends from school?</h3>
A fraction is a non-integer that has a numerator and a denominator. The numerator is the number that is above the line and the denominator is the number below the line. An example of a fraction is 5/12.
In this question, the numerator is the number of parts he gives his friends from school. The denominator is the total number of parts he divides the poster.
Fraction = parts he gave his friend from school / total number of parts
5 / 12.

The answer is currently A so yep thats the answer ok
Ok
in a 30-60-90 right triangle, if the leg oposite the 30 degree angle is x then the hypontuse is 2x
if the leg oposite the 30 degree angle is 12 inches then the hypontuse is 12*2 or 24 inches
