Find the values of x and y
PSYCHO15rus [73]

Hi there!

So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.


Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.

So the value of x is : 7


And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.

So the value of y° is : 60°


There you go! I really hope this helped, if there's anything just let me know! :)

(I WILL MATK BRAINLIEST)Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Jobisdone [24]

Answer:

  • 10m + 7n - 14

Step-by-step explanation:

<u>Given</u>

  • Q = 7m + 3n,
  • R = 11 - 2m,
  • S = n + 5,
  • T = -m - 3n + 8

<u>Simplify [Q - R] + [S - T]</u>

  • (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
  • 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
  • m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
  • 10m + 7n - 14
