by angle sum property in traingle having \angle x,

$50+70+x=180 \implies x=60^{\circ}$

now, by exterior angle property of triangle, $x+y=60+50$

put $x=60$ to get $y=50$

Here,

x+50°+70°= 180° [°.°Angle sum of triangle]

↪x= 180°-120°

↪x=60°

.°. x = 60°

Now,

Let z be the unknown angle of the second triangle

z+60°+50°=180° [°.° Angle sum of triangle ]

↪z=180°-110°

↪z=70°

. ° . z=70°

Then,

z+x+y= 180°

↪70°+60°+y=180°

↪y=180°-130°

↪y=50°

.°.y = 50°

Which is the best estimate for the sum 3/8 and 1/12
andrew11 [14]
When you want to add fractions with different denominators-which are the bottom numbers- you have to find the lowest numbers that you can multiply to go into both numbers.  I know that you can multiply 8×3 to get 24.  And that I can multiply 12×2 to get 24.  So 24 would be what we change the denominators to.  

But we can't just change the denominators.  I have to change the numerators, too.  Since I multiplied 8×3, I have to multiply the numerator by 3, also.  3×3=9.  The new fraction is \frac{9}{24}.  

Do the same thing to the other fraction. But we will multiply by 2. 1×2=2.  So now we have \frac{2}{24}.  We can now add.

\frac{9}{24}+\frac{2}{24}  Only add the top numbers.  We have \frac{11}{24}That fraction cannot be reduced, so \frac{11}{24} is the final answer.
