The answer is 1/4. Hope I could help! :D
A. Other crops: 35+25+20=80%
Beans: 100-80=20%
B. 300 acres×20%
=60 acres of cotton
C. Corn: 300×35%= 105 acres
Wheat: 300×25%= 75 acres
105-75= 30 more acres of corn than wheat
D. Yes, he is correct.
Corn fields+bean fields
35%+20%= 55%
They each go up by 5 :) 2+5=8 8+5=14 etc.
Answer:
Apply trigonometric function for triangle ABC:
7.
sin A = BC/BA = 6/7.2 = 0.83
A = arcsin(0.83) = 56.44
8.
tan B = AC/BC = 4/6 = 0.67
B = arctan(0.67) = 33.69 deg
Hope this helps!
