Answer: Secant of angle A = √2
Step-by-step explanation:
From the given right angle triangle,
AB represents the hypotenuse of the right angle triangle.
With m∠B as the reference angle,
AC represents the adjacent side of the right angle triangle.
BC represents the opposite side of the right angle triangle.
To determine Cosine of m∠A, we would apply
the cosine trigonometric ratio.
Cos θ = adjacent side/hypotenuse. Therefore,
Cos A = √5/√10
Secant = 1/Cosine
Therefore,
Secant of angle A = √10/√5 = √2
Answer:
C
Step-by-step explanation:
Divide the numbers 42 divided by 6 and 28 divided by 4
=7+7
=14
14 does not equal 28
Answer:
<h2>They form concentric circles.</h2>
Step-by-step explanation:
The complete question is
<em>Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating machine platform:
</em>
<em>The plate is rotated 270° about the origin in the counterclockwise direction. Which of the following is formed when the arcs of rotation are drawn for each point as it is rotated?
</em>
<em>
</em>
<em>They form parallel segments.
</em>
<em>They form perpendicular segments.
</em>
<em>They form concentric circles.
</em>
<em>They form congruent segments.</em>
<em />
<em />
Each vertex of the trapezoid will create a circle, where the center is the origin (0,0). As you can deduct, all circles will have the same center, which means the circles will be concentric. <em>Remember that concentric means one inside the other.</em>
Therefore, the right answer is <em>They form concentric circles.</em>
