Ответ:
x = 33°
Step-by-step explanation:
All angles in a triangle add up to 180°.
Step 1: Set up equation
x + 114 + 33 = 180
Step 2: Solve for x
Combine like terms: x + 147 = 180Subtract 147 on both sides: x = 33Ответ:
it means. F(K) =25,64 for some value of k
for 25
25=k²+2k+1
k²+2k-24=0
k²+6k-4k-24=0
K(k+6)-4(k+6)=0
(k-4)(k+6)=0
k=-6,+4
for 64
k²+2k-63=0
k²+9k-7k-63=0
k(k+9)-7(k+9)=0
(k-7)(k+9)=0
k=-9,+7
so the domain of F(k)={ -9 , -6 , 4 , 7 }
