S=θr
10.91=θ5
10.91/5=θ
therefore
θpie/180= your answer in radians
1,000 x 2= 2,000
2,000/1=2,000
2,000 - 29 = 1,971
Answer:
45
Step-by-step explanation:
by the definition of an isocoles triangle, defined by having two congruent sides, (p-s, r-s), angles SPR and SRP are congruent. by the triangle sum theorem, (internal angles + to 180˚) 90˚ + 2a = 180˚. 2a =90, a = 45
