In triangle STU, u2 = s2 + t2. Triangle STU has sides s, t, u opposite to the corresponding vertices S, T, U Which equation is t
wlad13 [49]
Answer:
<span>The measure of angle SUT is equal to 90 degrees
</span>
Explanation:
The Pythagorean theorem states that:
"In any right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides"
In other words:
(hypotenuse)² = (first side)² + (second side)²

Now, for the given, we have:
u² = s² + t²
This means that the given triangle UST is a right-angled triangle and that side "u" is its hypotenuse.

According to the given, the angle opposite to side "u" is angle U. This means that angle U is the right-angle in this triangle.

Based on the above:
angle U = 90°
angle S + angle T = 180 - 90 = 90°

Now, comparing our deductions to the given choices, we can conclude that the correct choice is:
The measure of angle SUT is equal to 90 degrees

Hope this helps :)

Solve for x. Enter the solutions from least to greatest. 3x^2 – 33x + 54 = 0
GarryVolchara [31]

Answer:

Step-by-step explanation:

3x² - 33x + 54 = 0

Divide the whole equation by 3

x²- 11x + 18 = 0

Sum = -11

Product = 18

Factors = -9 , -2              { - 9 + (-2) = -11  ; (-9) *(-2) = 18}

x² - 2x - 9x  + -9 * -2 = 0

x(x - 2) - 9(x - 2) = 0

(x-2)(x-9) = 0

x - 2 = 0   ; x - 9 = 0

x = 2  ;x = 9

Lesser x = 2

greater x = 9

You randomly draw a marble from a bag of marbles that contains 333 blue marbles, 444 green marbles, and 555 red marbles.
Nikitich [7]

Answer:

1/4 or 0.25

Step-by-step explanation:

Isn't latex a devil?

You want to know the probability of a blue marble.

Formula

P(blue) = #Blue / # Total

Givens

#Blue = 333

#Total = 333 + 444 + 555 = 1332

Solution

P(blue) = 333 / 1332      Divide by 111

P(blue) = 3/12

P(blue) = 1/4 or 0.25
