Solving for the angles, we need to apply and use Law of Cosines:
Solving for ∠AB, we have
cos ∠AB = (BC² + CA² - AB²) / 2*BC*CA
cos∠AB = (9²+17² -13²) / 2*17*9
∠AB = 48.94°
Solving for ∠BC, we have
cos ∠BC = (AB² + CA² - BC²) / 2*AB*CA
cos∠AB = (13²+17² -9²) / 2*17*13
∠BC = 31.47°
Solving for angle CA, we have:
∠CA = 180° - 31.47° - 48.94°
∠CA = 99.49°
The smallest angle is 31.47°.

Answer:
120
Step-by-step explanation:
As we can see that if we divide 120 by the 24, the remainder would be zero and the quotient be 5
As if we multiply 24 with the 5 it gives 120
And, the 4 is not a digit as it smaller than 24 so we have to carry the amount
Therefore if we insert 120 and divisible by 24 than it gives quotient 5 and the remainder is zero as it is completely divisible
-2x+6=-8+10x
12x=14
6x=7
x=7/6
