Answer:

  acute triangle, obtuse triangle

Step-by-step explanation:

The sums of interior angles of all triangles are 180°, but the triangles are only similar if their corresponding angles are congruent.

An acute triangle and an obtuse triangle both have angle sums of 180°, but can never be similar to one another.

3. Let w (x)= 4x + 3 and h (w)= x +1. What is the composition w (h (x))?
Stella [2.4K]

\text{ Hello there! :)}

\large\boxed{w(h(x)) = 4x+ 7}

w(h(x) = \\\text{Substitute in the equation of h(x) into "x" of the equation w(x):}\\\\w(h(x)) = 4(x + 1) + 3\\\\\text{Simplify:}\\\\w(h(x)) = 4x + 4 + 3\\\\w(h(x)) = 4x + 7

Answer:

The image is (-18,0)

Step-by-step explanation:

Here, we want to find the image of the given point after dilation by the given scale factor

Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;

(kx , ky)

Applying this in the given scenario, we have

(2(-9) , 2(0))

= (-18,0)

A quadrilateral PQRS is inscribed in a circle, as shown below: A quadrilateral PQRS is inscribed in a circle. The measure of ang
nydimaria [60]
Arc PQR measures 210°

An intercepted arc measures twice the intercepted angle. Here, the intercepted angle is ∠PSR. Hence:
Arc PQR = 2 * ∠PSR

1.) Compute for ∠PSR first. Opposite angles in a quadrilateral measures 180°. Hence:
∠PQR + ∠PSR = 180°
     75° + ∠PSR = 180°
               ∠PSR = 180° - 75°
               ∠PSR = 105°

2.) Proceed with computing Arc PQR:
Arc PQR = 2 * ∠PSR
               = 2 * 105°
               = 210°
