Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A \sqrt4, 10,
Vika [28.1K]

Answer:

(C)      

Step-by-step explanation:

In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.

A. \sqrt{4}, 10 and 116

According to Pythagoras theorem,

⇒(116)^2=4+100

⇒13456=104

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

B. 3,6 and 8

According to Pythagoras theorem,

⇒(8)^{2}=(3)^2+(6)^2

⇒64=9+36

⇒64=45

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

C. 30, 40 and 50

According to Pythagoras theorem,

⇒(50)^{2}=(30)^2+(40)^2

⇒2500=900+1600

⇒2500=2500

which satisfies the condition, therefore theses side lengths form right triangle.

Pls help I’m stuck on this question
dimulka [17.4K]
Answer: B) y=1/4x+7/2

Step 1: Slope

Knowing that the equation will be perpendicular to the one given will only give us the slope. Perpendicular means that the slope will be opposite to what it is now.

The opposite of -4 (the current slope) is 1/4. Even knowing only this will tell us that the answer is b, but I will continue to explain for when no options are given.

Step 2: Y-intercept

Now that we know the slope, the perpendicular aspect of this equation will no longer be of any help.

To find the y-intercept, we need to substitute y and x with the point given.

Our current equation is— y= 1/4x+b

Let’s substitute the point into this. The point (-2,3) tells us that the y-value is 3 and the x-value is -2.

y= 1/4x+ b

3=1/4(-2)+b

3 = -1/2 +b
+1/2 +1/2
__________
3 1/2 =b

Step 3: Improper fraction

Being that it is preferred to leave fractions improper, let’s turn 3 1/2 into an improper fraction. This will turn into 7/2 (comment below if you need an explanation of how to do this)

Final answer: now that we know that the slope is 1/4 and the y-intercept is 7/2, we know that our equation will be y=1/4x+7/2

Hope this helps comment below for more questions:)
