Answer:
58 degrees
Step-by-step explanation:
The little square in the corner signals a right angle/a 90 degree angle. If x and 32 add up to 90, then x is 58.
The equation whose solution is the given quantity is 90,000,000 = 2,000,000w + 15,000w where w = $44.67
<h3>Equation</h3>
B = xz + yw
Where,
- B = Total cost = 90
- x = number of fighter plane = 20
- y = tons of wheat = 15,000
- w = cost of each tons of wheat
- z = cost of fighter plane
- z = 100,000w
B = xz + yw
90,000,000 = (20 × 100,000w) + (15,000 × w)
90,000,000 = 2,000,000w + 15,000w
90,000,000 = 2,015,000w
w = 90,000,000 / 2,015,000
= 44.6650124069478
Approximately,
w = $44.67
