Answer:
48.8 lbs
Step-by-step explanation:
The forces can be modeled by a triangle with acute angles 20° and 26°, and obtuse angle 134° opposite a side of length 80. The larger component force will be opposite the angle 26°, and can be found using the Law of Sines:
a/sin(A) = c/sin(C)
x/sin(26°) = 80/sin(134°)
x = 80sin(26°)/sin(134°) ≈ 48.753 . . . . pounds
The larger component force is about 48.8 pounds.
M^7
add the exponents together.
To be equal to 1, both the numerator and denominator need to be the same.
12/12 would be equal to 1.
20
a^2+b^2=c^2
The sum of angles on a straight line is 180 degrees.
Therefore,
tan(26)=42/x hence x=42/tan(26)=86.113
