1.
4x^2 + 20x
= 4x(x + 5)

2.
x^2 - 12x = 64
x^2 - 12x - 64 = 0
(x - 16)(x + 4) = 0
x - 16 = 0 or x + 4 = 0
x = 16 or x = -4
x = {-4, 16}

PQR has two known interior angles of 34°, and 80°. △RST has two known interior angles of 24°, and 90°. What can be determined ab
Shalnov [3]

Answer:

△PQR and △RST are not similar.

Step-by-step explanation:

In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is

180-34-80=66

In triangle △RST, two known interior angles are 24° and 90°.

180-24-90=66

Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.

Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.

Which of the following sets of points are vertices of a right triangle?
grandymaker [24]

  • Please find the picture for your triangle.
  • We know, area of a ∆ = <u>1/2 × base × height</u>
  • Here, base = ( 1 + 7 ) units = <u>8 units</u>
  • Height = ( 7 - 1 ) units = <u>6 units</u>
  • Therefore, area of the ∆
  • = <u>(1/2 × 8 × 6) square units</u>
  • = <u>24 square units.</u>

<u>Answer</u><u>:</u>

<em><u>2</u><u>4</u><u> </u><u>square </u></em><em><u>units</u></em>

Hope you can get an idea from it.
