Answer:
Step-by-step explanation:
take 51 degree as reference angle
using sin rule
sin 51=opposite/hypotenuse
0.77=YZ/9
9*0.77=YZ
6.93=YZ
6.9=YZ
This can be solved using the pythagorean theorem. The theorem is shown below:
c^2 = a^2 + b^2
The hypotenuse is c, so substituting the given values:
c^2 = (5)^2 + 12^2
c^2 = 25 + 144
c = sqrt(169)
c = 13
Therefore, the correct answer is B. 13 cm.
A. 168 explaination: 4* 3= 12 meaning 56 times 3 would be 168
X>8
Sarah has more than eight goldfish in her tank
Answer:
x = 4/3
Step-by-step explanation:
To solve find f(4x) and f(x+4). You should get f(4x) = 4x + 5 and f(x+4) = x + 9. Now, set the two equations equal to each other.
f(4x) = f(x + 4)
4x + 5 = x + 9
3x = 4
x = 4/3
