Answer:
240°
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°, so you have ...
a° +b° +60° +60° = 360°
a° +b° = 240° . . . . . . subtract 120° from both sides
Answer:
Step-by-step explanation:
<u>The distance is:</u>
<u>Return trip will take:</u>
- 480/75 = 6.4 hours = 6 hours and 24 min
First step: name the sides according to geometry standards, namely, the sides are named the same lowercase letter as the opposing angle. A revised diagram is shown.
Second step: we need to know the relationships of the trigonometric functions.
cosine(A)=cos(63) = adjacent / hypotenuse = AC/AB .................(1)
sine(A)=sin(63) = opposite / hypotenuse = CB/AB .......................(2)
We're given AB=7, so
using (1)
AC/AB=cos(63)
AC=ABcos(63)=7 cos(63) = 7*0.45399 = 3.17993 = 3.180 (to three dec. figures)
Using (2)
BC/AB=sin(63)
BC=ABsin(63) = 7 sin(63) = 7*0.89101 = 6.237 (to three dec. figures).
