Answer:
3.1 ft
Step-by-step explanation:
You need to use the Pythagorean Theorem to solve for the leg of the triangle and then double that answer to get the length of the entire line of "x".
a²+b²=c²
1.4²+b²=2.1²
1.96+b²=4.41
b²=2.45
b=1.565247584249853 (this is the leg of the triangle)
now multiply by 2
x=3.130495168499706
Round to nearest tenth
3.1 ft
Answer:
8 + 16k
Hope this helps
Step-by-step explanation:
Switch sides
Abc=d
Now divide both sides by bc to get a .
A= d/bc
Answer:
Step-by-step explanation:
Given the equation 
Step 1;
Expand the bracket at the right hand side of the equation to have:
Taking the reciprocal of both sides:
Answer:
Step-by-step explanation:
Side c = AB can be found using the Pythagorean theorem:
c² = a² + b² = 8² +5² = 89
c = √89 ≈ 9.43
__
Angle B is the complement of angle A, so is ...
B = 90° -A = 90° -58° = 32°
c is approximately 9.43; the measure of angle B is 32°.
