Answer:

x = 4

Step-by-step explanation:

An equilateral triangle means that all three sides are equal. All triangles have an inner angle measure of 180 degrees. Divide 180 by 3 to find out a singular angle's measure. You end up with : 10x + 20 = 60. In order to isolate the 10x, subtract 20 from both sides. This gives you 10x = 40. Thus, x = 4.

Whe might you read 0.203 as 2 tenths 3 thousandths
MAVERICK [17]
Well, sometimes it is needed in word form. If someone asks you how much money you need in debt, you might say 1 tenth 4 hundredths. That is why you might need to read 0.203 as 2 tenths 3 thousandths.

GEOMETRY QUESTION, HELP PLEASEEE.
choli [55]

Answer:

The pre-image C is (2, 5)

Step-by-step explanation:

  • If the point (x, y) rotated about the origin by angle 90° clockwise, then its image is (y, -x)
  • If the point (x, y) rotated about the origin by angle 180° clockwise, then its image is (-x, -y)
  • If the point (x, y) rotated about the origin by angle 270° clockwise, then its image is (-y, x)

∵ Point C was rotated 270° clockwise around the origin

∵ C' = (-5, 2)

→ By using the 3rd rule above

∵ The image of the point (x, y) is (-y, x)

∴ (-y, x) = (-5, 2)

→ That means -y = -5 and x = 2

∴ x = 2

∴ -y = -5

→ Divide both sides by -1

∴ y = 5

∴ The pre-image C = (2, 5)
