The sum of the interior angles of a triangle is always 180 degrees. Thus,
the sum of 31, x+4 and 3x+9 must be 180.
31 + x + 4 + 3x + 9 = 180, or 44 + 4x = 180
While it's not necessary, y ou could reduce this equation before solving for x:
11 + x = 45. Then x = 34 degrees.
The three angles are then:
31
34+4 = 38
3(34) + 9 = 111
Check: show that 31+38+111 = 180 (degrees)
Z is congruent to X because they are across from each other on the triangle, so angle z is 30°. hope this helped, please give brainliest
Let cranberry juice be x.
Let citrus fruit juice be y.
x + y = 630
x + 0.1y = 630*0.23
Solving this yields,
x = 91
y = 539
Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.
Hope this helps.:)
