Sum of all the angles in a triangle = 180 degrees.
it's given is an acute angle so <90
degrees now one is 38 the sum of other two would be 142 now here 27 is not possible because then the third angle, would be 115 degrees.
hope this help
Answer: 1 & 1/2
The whole part is 1
The fractional part is 1/2
======================================================
Explanation:
Write 1/2 as 2/4. Basically you multiply top and bottom by 2.
We have these three fractions: 1/4, 2/4, 3/4
Add them up: (1/4)+(2/4)+(3/4) = (1+2+3)/4 = 6/4 = 3/2
To go from 6/4 to 3/2, we divide both parts by 2.
Finally, convert the improper fraction 3/2 to the mixed number 1 & 1/2
125+85+22.5+22.5+65=320
320x0.06=9.2
12x10=120
320+19.2+120=459.2
13 - 4 = 9
9 squared = 81
Top part of the fraction = 81
8 ÷ 4 = 2
Bottom part of the fraction = 2
Facctore each
5y^2=5*y*y
80=5*2*2*2*2
lcm of those are
5
5(y^2-16)
we can factor this difference of 2 perfect squares
5(y-4)(y+4)
y+4 is the other one
so the lcm is 5y^2-80
