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 :)

an employess new salary is 28,140 after getting 5% raise what was salary before increase _and what was last years salary _?
jonny [76]
He got a 5% raise, so 28,140 is 105% of what it used to be.

105% means 1.05

(1.05) x (salary before increase) = 28,140

Divide each side by 1.05 :

Salary before increase = 28,140 / 1.05 = <u>26,800</u> .

The rest of the question is nonsense. The salary
before increase IS last year's salary.

What is 15% of $10.00
Katarina [22]
In mathematics, the word 'of' always means multiplication, so to find out what 15% of $10.00 is, all we need to do is multiply the percentage by the dollar amount we are reducing.

In order to do this, we must first convert the percentage into a decimal. To do this, we can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.

15% = 0.15

So now, we can multiply.

0.15 * 10 = 1.5

which is our answer.
15% of $10.00 is $1.50.
Hope that helped! =)
