What is the side length of a when b=7 and c=4 and the angle opposite side a is 32°? ROUND TO THE NEAREST TENTH.

a=72+42-2(7)(4)cos32

a=49+16-56cos32

a=65-56cos32

17.5°

Turbo🐌 is looking up at a crow at a 29° angle. He is the same speed as the crow. The crow wants to reach his house before he does. Turbo is 85 feet away. Will Turbo make it to his house first?

tan 29°=x/85 

x=tan 29°/85

x=47.11626937

He will not even be close to making it. 🤤🐦‍⬛😵

In a 30, 60, and 90 triangle what is the distance of the hypotenuse? (use x as your variable)

2x  

400

A set of three non zero whole numbers that satisfy the equation a2+b2=c.

Pythagorean Triple 

400

Using the Law Sines where you want to find a in triangle ABC where angle A=72° and angle B=34° and side b= 9 units. ROUND TO THE NEAREST tenth.

sin 72/a=sin34/9

a= 9 sin 72/ sin 34

a=15.3 units

Riley is standing 120 feet above on a hot air balloon and looks down at a hybrid cat-dog  at and angle of 32° how far away is Riley from the cat-dog? 🐱🐶

cos 48= 120/x  

x= 120/cos 48

x=179.337186

too  farrrr 😪

A plane takes off 14 miles from a 5 mile high cliff. The plane climbs at 16 degrees, will the plane make it over the Cliff?

Tan16= x/14 x=Tan16(14)  x=4.01 so yes it will clear the cliff because the cliff is 5 miles high.
