When a triangle is a 45-45-90 triangle, the following rules apply:

-the 2 legs are equal lengths
- the length of the hypotenuse is: the square root of 2 x the length of a leg.
- the length of the leg is: hypotenuse divided by the square root of 2.

if the hypotenuse is 10, then 10 divided by the square root of 2 is how you find the leg.
the square root of 2 is <span>1.41421356237. 
10 divided by </span>1.41421356237 is <span>7.07106781188, which can be rounded to about 7.1. The length of one leg is about 7.1 units!</span>

WITCHER [35]

Answer:

Step-by-step explanation:

The translation vector < 4, - 2 > means each point is being moved 4 units to the right and 2 units down.

X(0, 3) ------> X' ( 0 + 4, 3 - 2 ) = X'(4, 1)

Y( - 1, 1) ------> Y' ( - 1 + 4, 1 - 2 ) = Y'(3, - 1)

Z( - 3, 4) -----> Z' ( - 3 + 4, 4 - 2 ) = Z'(1, 2)

Can Someone Explain??
ValentinkaMS [17]
A) Dependent Variable = Sue's Earning
Independent Variable = Number of hours she work

Y = 6x

B) When, x = 1, y = 6(1) = 6, 
when x = 2, y = 6(2) = 12
when x = 3, y = 6(3) = 18

Ordered pairs would be: (1, 6), (2, 12), (3, 18)

C) Equation would be: Y = 6x
Where, y = Earning
x = number of hours

Hope this helps!

First angle in the triangle is 52 degrees Celsius and I need to find the outside and top
Margaret [11]

In figure,

AC = BC (given)

Since, in a triangle , angles opposite to equal sides are also equal.

Therefore,

b= 52°

Now,

°.° c is exterior angle of triangle.

.°. c = b + 52°

=> c = 52° + 52°

=> c = 104°

Solution:-

-------------

b = 52° & c =104°
