Answer:
Side A = 14; Side B = 24.25; Side C = 28 |
Angle A = 60 degrees; Angle B = 30 degrees; Angle C = 90 degrees
Step-by-step explanation:
Okay, I find this question a bit weird because you already have two sides
So, I'm going to assume:
Side A = 14
Side B = 24.25
<h3>Finding side C</h3>
Using Pythagoras theorem
c = 28 units (28.00111605)
<h3>Finding Angles (A,B and C)</h3>
In the diagram, we can see there is a right angle triangle, and a little square
Therefore, we can say that Angle C is 90 degrees
Finding Angle A/B:
There are so many ways to find it, I'll just use this though
<h3>Method: Using SOHCAHTOA to find B, then finding A</h3>
Using SOHCAHTOA
I'll be using the sine rule to find Angle B
Angle B = 30 degrees
The interior angles in a triangle add up to 180 degrees
Angle A = 180 - (90 + 30)
Angle A = 60 degrees
Verify:
60 + 30 + 90 = 180
Answer:
the quantities do NOT vary directly
Step-by-step explanation:
A graph showing a proportional relationship is a straight line through the origin. This graph goes through (0, 100), so does NOT show a proportional relationship. y does NOT vary directly with x.
