The answer is 130 degrees
Answer:
40 degrees
Step-by-step explanation:
The sum of the angles is 180.
A 100 degree angle cannot be a base angle because then
the sum of the base angles would be 200 degrees.
The 100 must be the vertex angle.
Equation:
x + x + 100 = 180
2x = 80
x = 40 degrees.
Each of the base angles is 40 degrees.
Answer:
6
Step-by-step explanation:
b = 2 units
h = 6 units
A=1/2 *b*h
= 1/2 *6*2
= 6
Answer:
78.4 ft
Step-by-step explanation:
Part I:
Missing angle = 180° - (130 + 30) (sum of angles in a triangle)
= 180° - 160°
Missing angle = 20°
Part II: distance (d) from Swanson to the boat
Law of Sines is given as:

Where,
a = d
A = 130°
b = 35 ft
B = 20°
Plug in the values and solve for d

Multiply both sides by sin(130) to make d the subject of the formula
