Answer:
∠5
Step-by-step explanation:
A linear pair of angles create a straight line
The only angle that creates a straight line with ∠1 is ∠5 therefore cyan is the answer
Answer:
25.12
Step-by-step explanation:
Answer:
b =15
Step-by-step explanation:
We can use Pythagoras theorem to find b:
![a^{2}+b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%2Bb%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
![8^{2} + b^{2} = 17^{2}](https://tex.z-dn.net/?f=8%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%2017%5E%7B2%7D)
64 +
= 289
64 + 225 = 289
64 +
= 289
b = 15
hope this helps :) and sorry if not right
First convert x^2 + 10x - 9 to vertex form and you will get
f(x) = (x-5)^2 - 34 This means that the vertex must be (5, 34)
Step-by-step explanation:
By definition, the area of a rectangle is given by:
A = w * lA=w∗l
Where,
w: width of the rectangle
l: length of the rectangle
We then have the following expression for the area:
A = k ^ 2 + 19k + 60A=k
2
+19k+60
What we must do is factorize the expression following the following steps:
1) Find two numbers that are equal to 19
2) Find two multiplied numbers equal to 60
We have then:
A = (k + 15) (k + 4)A=(k+15)(k+4)
Therefore, the width of the rectangle is:
w = (k + 4)w=(k+4)
