How are patterns used to solve problems?

1 answer:

3 0

Patterns can help muliply and divide. For an example say your problem is 6x2 you can do 2+2+2+2+2+2. Or if your problem is 21 divided by 3 you could do 21-3 untill you get to zero and count how many time you had to subtract.

The sum of the angles of a quadrilateral is 360°.
$\left(\dfrac{3}{2}x+20\right)+\left(\dfrac{7}{2}x+20\right)+\left(\dfrac{5}{2}x+40\right)+\left(\dfrac{3}{2}x+10\right)=360\\\\9x+90=360\\\\x=\dfrac{270}{9}=30$

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115

The appropriate choice is ...
D) 115°
