Answer:
79
Step-by-step explanation:
The sum of the three interior angles in a triangle is always 180°
180-73-28 = 79
Step-by-step explanation:
Use the formula D2 = X^2 + Y^2 to find the squared distance between two points. If the two points have coordinates (-3, 7) and (1, 2), then the difference between 7 and 2 is 5, and so Y = 5. For example, if X = 4 and Y = 5, then D2 = 42 + 52 = 41. Thus, the square of the distance between the coordinates is 41.
y^2 means (y) x (y)
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
Answer:
Proved
Step-by-step explanation:
m∠JPO = 90 = m∠OWK, and angle O is common between both triangles [reflexive property]. Therefore by Rule AA, ΔOKW~ΔOJP
