Answer:
15:17
Step-by-step explanation:
Since the triangle has a right angle, we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side
CB is the hypotenuse side
and DC is the opposite side
Hence Sin B = 15/17
-- XY is a "diameter" of the circle.
-- A diameter is any straight line inside the circle that goes
through the center and touches the curvy part twice.
-- Every diameter of the same circle has the same length.
-- The distance around every circle is (its diameter) multiplied by (pi).
-- Half of the diameter is called the "radius" of the circle.
A radius is any straight line inside the circle that goes between
the center and the curvy part.
-- The area of every circle is (its radius, squared) times (pi).
-- 'Pi' ( π ) is a number. It's a decimal that keeps going forever
and never ends, so you can never write it exactly with numbers.
-- Pi is roughly 3.14 , and if you use 3.14 whenever you need pi,
then your answers will be about 0.05% too small.
That's very close. When you turn in an answer that's only
0.05% wrong, the teacher knows that you know how to solve
the problem, and that's way more important than the answer.
For the circle in your picture, the diameter is 17in, the radius
is 8.5in, and the area must be (pi) (8.5)² square inches.
You can go ahead and work that out.
The answer is 25, it moves 8 points x and 17 points y.
10-14 is -4. Think of it as 14-10=4 but you turn the 4 into a negative number. Hope that answers
The remainder will be;
3-(1.38+0.22)
=3-1.6
=1.4 pounds
