The angle sum in a triangle is 180
30 + 45 = 75
180 - 75 = 105.
The remaining angle measure is 105°.
I believe that expression would be in the form
ax²+bx +c where, c is the constant term
For example; in the expression;
2x²+3x²+7 , 7 is the constant term.
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Volume of an excavation = 203 cubic feet
Weight of the material = 1200 pounds per cubic yard
So, the weight of the excavation would be
Volume of an excavation × Weight of the material

Hence, the weight of the excavation is 243,600 pounds.
Therefore, Option 'd' is correct.
Answer:
Step-by-step explanation:
About 12% of the land is arable and less than 6% currently is cultivated. Normally, Afghanistan grew about 95% of its needs in wheat and rye, and more than met its needs in rice, potatoes, pulses, nuts, and seeds; it depended on imports only for some wheat, sugar, and edible fats and oils. Fruit, both fresh and preserved (with bread), is a staple food for many Afghans. Agricultural production, however, is a fraction of its potential. Agricultural production is constrained by an almost total dependence on erratic winter snows and spring rains for water; irrigation is primitive. Relatively.
That is true. It is the Pythagorean Theorem.
