Answer:
D) 112°
Step-by-step explanation:
Reflection is a type of transformation that require the turning of a point or an object about a reference point line.
In the given question, when the point is first reflected about l, it rotates at an angle of 56°. Then reflecting it about m give a total rotation of 112° by the point. Thus, the point (-4, 1) is rotated twice the angle between lines l and m.
Just let every x in f(x) be g(x)
it means:
f(g(x))=(2x^2+5)^2+(2x^2+5)+2
=4x^4+20x^2+25+2x^2+5+2
=4x^4+22x^2+32
We can find the approximate measurement of angle ABC and it is equal to 180°. The summation of all angles in a triangle is 180°.
Solving for x or angle B, we need to used Pythagorean theorem and SOH CAH TOA.
Solving for angle A:
sinA = 10.5/20
A = 31.67°
Solving for angle B:
180° = ∠C + ∠B + ∠A
180° = 90° + ∠B + 31.67
∠B = 58.33°
The x value is 58.33°.
A translation of triangle XYZ is triangle B shifted by 7 units to left.
Given that, triangle XYZ (2, 4), (5, 5) and (3, 0).
<h3>What is translation?</h3>
A translation moves a shape up, down or from side to side but it does not change its appearance in any other way. Translation is an example of a transformation. A transformation is a way of changing the size or position of a shape. Every point in the shape is translated the same distance in the same direction.
We can see from given figure ΔXYZ and the triangle B are alike.
From ΔXYZ translated to triangle B by 7 units left.
Therefore, a translation of triangle XYZ is triangle B shifted by 7 units to left.
