Answer:
34⁰
Step-by-step explanation:
let unknown angle be x
cos x=19/23
cos x=0.826
x=cos inverse of 0.826
x=34.3⁰
Answer:
D : One Real Root
Step-by-step explanation:
Isolate "4x" by subtracting 7 from both sides.
So we get
4x = -7
Then we divide each side by 4 to get -7/4
x = -7/4 so there is only one real root.
The coordinates of the school is now (5,7).
F(2a)=35
35=(2a)^2-1
35=4a^2-1
minus 35 from both sidse
0=4a^2-36
facor out 4
0=4(a^2-9)
factor differece of 2 perfect squares
0=4(a-3)(a+3)
set to zero
a-3=0
a=3
a+3=0
a=-3
a=-3 or 3
