Answer:
the angle of inclination of the hill is 46.56°
Step-by-step explanation:
Given the data in the question;
Just as illustrated in the diagram below
so to find the angle of inclination of the hill;
sinA/30 = sinB/125
since angle BAC is 8°
we substitute
sin8°/30 = sinB/125
sinB = ( sin8°/30 ) × 125
B = sin⁻¹ ( ( sin8°/30 ) × 125 )
B = sin⁻¹ ( 0.004639 × 125 )
B = 35.44°
so since the some of a the angles of a triangle is 180;
A + B + C = 180
8° + 35.44° + C = 180
C = 180 - ( 8° + 35.44° )
C = 136.56°
Hence, Angle of inclination x will be;
x = 136.56° - 90°
x = 46.56°
Therefore, the angle of inclination of the hill is 46.56°
Answer:
62 1/4 = 62.25
Step-by-step explanation:
Turn the improper fraction into a mixed number then divide as an equation.
62 x 4 = 248
248 + 1 = 249.
Put the 249 over the 4 and divide.
249/4 = 249 ÷ 4 = 62.25
Multiplying binomial and polynomials can be easy as long as you follow the steps for example:
Let's say you were multiplying 3x-3 and x+2
(3x-3)(x+2)
remember FOIL
OR think about it like this(see attatchment)
3x^2 + 3x -6 is what you should get
If Bamboo is in the family Poaceae, and all plants in Poaceae are grass, then Bamboo is a type of grass, meaning the correct answer is B. Bamboo is a type of grass.
Answer:
32-26i
Step-by-step explanation:
(4+3i)(2-8i)
8+6i-32i-24i^2
8-26i-24(-1)
8-26i+24
-26i+32
Remember that i^2=-1.
