Sum of interior angles in a triangle = 180
so
2y + y+10 + 50 = 180
3y + 60 = 180
3y = 120
y = 40
Answer is A. 40
Answer:
18
Step-by-step explanation:
1/3 of 27 is 9 so 2/3 is 18
First do with the factor out variable m.
m(k+q)=t
Next divide both sides of k+q.
m(k+q)/k+q= t/k+q
Answer is m=t/k+q
Step-by-step explanation:
From the Pythagorean theorem we have:
<em>subtract b² from both sides</em>
Same:
40 cm.
let the length of the first part be 3x, second part be 4x, third part be 5x.
where x is a positive length in cm.
why 3x,4x and 5x ?
so that the ratio of lengths of the 3 parts be 3:4:5.
total length of the stick = 3x + 4x + 5x = 12x=96cm
so x=96/12 = 8cm
therefore the largest part of the stick (5x)= 5*8 =40cm
