Aisha and brendan are watching a hot air balloon. the angle of elevation for aisha is 65 degrees. what is the angle of elevation for brendan?

The angle of elevation for Brendan is  40°

Step-by-step explanation:

To find the angle of elevation of Brendan, we will follow the steps below;

we can use the sine formula to find the angle of elevation of Brendan since we were given two sides and one angle

Using the sine rule;

=

From the diagram above, angle A = 65°     side a = 155 m   side e=110 m

angle E is what we are to find

we can now proceed to insert the values into the formula

 =  

cross-multiply

155 sinE = 110 sin65°

Divide both-side of the equation by 155

sin E = 110 sin65° / 155

sin E =0.64319

Take the sin⁻¹  of both-side of the equation

sin⁻¹ sin E = sin⁻¹ (0.64319)

At the left-hand side of the equation sin⁻¹ will cancel-out sin leaving us with just E

E =  sin⁻¹ (0.64319)

E= 40°

The angle of elevation for Brendan is  40°
