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
Answer:
x = 70
y = 40
Step-by-step explanation:
First, we need to find the measure of x.
As x and the angle 110 share a line, they must add up to 180 degrees. This means that the measure of x is 70.
The two ticks on the sides of the triangle indicate that these sides are equal in length. This also means that the corresponding angles will also be equal. This means that both x and the other angle are 70.
This means that we have two of the three angles in the triangle, so we can easily find the third, which is y.
