Answer:x = 6/5
Step-by-step explanation:
The given expression is
2/3+1/5x=5/6
The Lowest common multiple of 2, 5x and 6 is 30x. We would multiply the left hand side of the equation and the right hand side of the equation by 30x. It becomes
2/3 × 30x + 1/5x × 30x = 5/6 × 30x
= 20x + 6 = 25x
Subtracting 20x from the left hand side and and the right hand side of the equation, it becomes
20x - 20x + 6 = 25x - 20x
5x = 6
x = 6/5
We know that
applying the law of cosines
a² = b²+ c²<span> – 2*b*c*cos(A)
cos (A)=[b</span>²+c²-a²]/[2*b*c]
in this problem
a=10
b=17
c=18
so
cos (A)=[17²+18²-10²]/[2*17*18]-----> cos (A)=0.8382
A=arc cos (0.8382)-----> A=33.05°-----> A=33°
the answer is
33 degrees
