Notice the picture below

so, the two triangles are similar by AA

thus \bf \cfrac{x}{4}=\cfrac{125}{20}  solve for "x"

Angle D and Angle F are supplementary. The measure of Angle D is (3x + 5), and the measure of angle F is (2x). What is the measu
olga55 [171]

Step-by-step explanation:

Two angles are called suplementary when their measures add to 180 degrees.

D+F= 180

3x+5+2x= 180

5x+5=180

5x= 175

x= 35°

angle D = 3x+5= 3(35)+5= <u>110°</u>

Find the horizontal and vertical intercepts for
allsm [11]

Here, we are required to find the vertical and horizontal intercepts for r⁴ + s² − r s = 16.

The vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.

According to the question;

  • the r-axis is the horizontal axis.
  • the s-axis is the vertical axis.

Therefore, to get the horizontal intercepts, r we set the vertical axis, s to zero(0).

  • i.e s = 0
  • the equation r⁴ + s² − r s = 16, then becomes;
  • r⁴ = 16
  • Therefore, r = ±2.

Also, to to get the vertical intercepts, s we set the horizontal axis, r to zero(0).

  • i.e r = 0.
  • the equation r⁴ + s² − r s = 16, then becomes;
  • s² = 16.
  • Therefore, s = ±4.

Therefore, the vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.
