Those two angles are complementary - which means they both give us 90 degrees. We know that all three angles in any triangle must be exactly 180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means that our triangle is a <u>straight triangle</u>. The figure will look more less like in the attachment.
Answer:
B) y = 9 x has Proportionality Constant = 9
Step-by-step explanation:
Two quantities P and Q are said to be PROPORTIONAL if and only if:
P ∝ Q ⇔ P = k Q ⇔
Here, k = PROPORTIONALITY CONSTANT
Given : k = 9
Now, let us consider the given expressions in which x ∝y
y = 81/3 x
Here,
So, here Proportionality Constant ≠ 9
y = 9 x
Here,
So, here Proportionality Constant = 9
y = 3 x
Here,
So, here Proportionality Constant ≠ 9
y = 1/9 x
Here,
So, here Proportionality Constant ≠ 9
Hence, only y = 9 x has Proportionality Constant = 9
