Answer:
-5.5
Step-by-step explanation:
The ladder and the outside wall form a right triangle
The length of the ladder is 97.8 feet
<h3>How to determine the
length of the
ladder?</h3>
The given parameters are:
Distance (B) = 22 feet
Angle of elevation (θ) = 77 degrees
The length (L) of the ladder is calculated using the following cosine ratio
cos(θ) = B/L
So, we have:
cos(77) = 22/L
Make L the subject
L = 22/cos(77)
Evaluate the product
L = 97.8
Hence, the length of the ladder is 97.8 feet

Answer:
5
Step-by-step explanation:
same x coordinate
length = 3 + 2 = 5
Answer:
All four Sets didn't work
Step-by-step explanation:
You should be doing hypothnose aka: a² + b² = c²
If they both equal that means they are a right triangle.
Set 1:
24² + 26² = 110²
576 + 676 = 10²
1252 = 12100
No
Set 2:
2² + 4² = 6²
4 + 16 = 6²
20 = 36
No
Set 3:
13² + 14² = 15²
169 + 196 = 15²
365 = 225
No
Set 4:
10² + 20² = 30²
100 + 400 = 30²
500 = 900
No
K = 2
-7k + 3 = -11
-3 = -3
-----------------
-7k = -14
-7 / -14
= 2
