Answer:
Step-by-step explanation:
<u>Area of triangle:</u>
We have the value of b but not h.
Added auxiliary segments which help to find the value of h.
<em>See attached for details</em>
- sin 40° = h/4
- h = 4 sin 40°
- h = 2.57 km
<u>The area is:</u>
- A = 1/2*6*2.57 = 7.71 km²
262.5 miles
explanation 1/4 is half of 1/2 so 52.5 is half of 105 and then 210 for an hour of travel
Triangles= 180°
One right angle= 90°
Given angle= 57°
x= missing angle
Find the missing angle by subtracting angles from 180°.
90° + 57° + x= 180°
147° + x= 180°
x= 33° which is an acute angle
ANSWER:
The missing acute angle is 33°.
