Triangle abc has angle measures as shown. angle a= x-5 angle b= 3x+30 c= 35. a)what is the value of x? show your work. b)what are the values of the two unknown angles? (show your work)

We know that the sum of the measure of the angles in a triangle is 180 degrees
so A+B+C=180
(x-5)+(3x+30)+35=180
x-5+3x+30+35=180 add like terms
4x=60=180
4x=120 divide both sides by 4
x=30
angle A=x-5=30-5=25
angle b=3x+30=90+30=120
angle C is 35

4hours and 40 mins she would be 120 meters high

The answer would be 7 cages
