The answers are A and D, because the definition of congruent shapes is that they are the exact same size and the same angle measures. Option A shows two right triangles, that are matching in size because of the lines on the lines showing the same size. Option d is correct because The three sides of triangle TUV match up with triangle WXY. Option C is incorrect because Angle B does not match angle G. Option b is incorrect because the triangles are not the same size.
I hope this helps!

dimaraw [331]

Answer:

318.6

Step-by-step explanation:

(3x-9) + (x+15) = 180

3x (x+15) -9 (x+15)

4x + 45x - 9x + 6 = 180

40x + 6 = 180

40x = 180 - 6

40x = 174

x = 4.34

(3x-9) = 4.34 * 3x-9 = 4.02

(x+15) = 4.34 + 15 = 19.34

180 - (4.02 + 19.34)

= 180 - 23.36

= 156.64

hope this answer helps!!

Use the Pythagorean identity on page 10 with x = 4 and y= 3 to generate a Pythagorean triple​
Dmitry [639]

Answer:

  c.  7, 24, 25

Step-by-step explanation:

For the formulas ...

  • a=x^2-y^2
  • b=2xy
  • c=x^2+y^2

we can use the given values of x and y to find the corresponding Pythagorean triple:

  a = 4^2 -3^2 = 16 -9 = 7

  b = 2·4·3 = 24

  c = 4^2 +3^2 = 16 +9 = 25

The generated Pythagorean triple is (7, 24, 25), matching answer C.

A store pays $10.56 fora map of Africa and marks the price up by
nignag [31]

Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>


Side note: Another way that you can do this is by simply doing 1.5(10.56).
