We know that
in a right triangle
cos θ=adjacent side angle <span>θ/hypotenuse
in this problem
</span>adjacent side angle θ=38 in
hypotenuse=40 in
cos θ=38/40
θ=arc cos (38/40)-------> 18.19°-------> 18°
the answer is
18 degrees
64/4 = 16
draw 4 stacks of 16 books
shade 3 stacks of the 16 which is equal to 3/4 or 75%
P(35) = -9p + 4 = -9(35) + 4 = -315 + 4 = -311
p(28) = 5p - 17 = 5(28) - 17 = 140 - 17 = 123
a + 34d = -311
a + 27d = 123
7d = -434
d = -62
Therefore, the commpm difference is -62.
Answer:
A=hb/2
To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2. Find the area of a triangle where height = 5 cm and width = 8 cm. A triangle is always half the area of a rectangle with the same height and width.
The square root of 100 is 10. Which is a whole number and whole numbers are rational numbers.
