The measure of one of the small angles of a right triangle is 18 less than twice the measure of the other small angle. Find the

Kipish [7]

Answer:

36° and 54°

Step-by-step explanation:

We are given that one of the small angles of a right angled triangle is 18 less than twice the measure of the other small angle.

We are to find the measure of both angles.

Assuming $x$ to be the other small angle, 8 less than twice the measure of the other small angle = $2x-18$ .

Summing all three angles up ti get:

$x+(2x-18)+90=180$

$3x=180-90+18$

$3x=108$

$x=\frac{108}{3}$

x = 36°

So other angle will be $2(36)-18=$ 54°.

The distribution of the number of graduate students over the past 13 years in the math department was:1 69 2 445 3 347 4 0269 1.

gtnhenbr [62]

Answer:

16 and 73

Step-by-step explanation:

The question is missing some data. The distribution of the number of students is represented on the following stem-and-leaf plot:

$\begin{array}{cc}1&69\\2&445\\3&347\\4&0269\\5&\\6&\\7&3\\8&\\9&\end{array}$

The numbers in the first column represent the tens and the numbers on the second column represent the units. The number of students over the past 13 years were:

16, 19, 24, 24, 25, 33, 34, 37, 40, 42, 46, 49, 73.

Therefore, the smallest and largest number of students were 16 and 73.

Which of the following could be the ratio of the length of the longer leg of a 30 60 90 triangle to the length of its hypotenuse

yan [13]

For 30 60 90 triangles, the ratio of the side lengths is
$\frac{1}{2} : \frac{ \sqrt{3} }{2} :1$
where the first is the shorter leg, the second is the longer leg, and the third is the hypotenuse (the longest side that doesn't form a 90 degree angle)

so the ratio of the longer leg to the hypotenuse is $\frac{ \sqrt{3} }{2} :1$
or
 $\frac{ \frac{ \sqrt{3} }{2} }{1}$
which equals $\frac{ \sqrt{3} }{2}$

2x + 5y = 17 what is x what is y

andrew-mc [135]

Answer:

x = (17 - 5y)/2

y = (17 - 2x)/5

Step-by-step explanation:

nothing else can be done here.

if you are looking for actual numbers as solution, then you have forgotten to put something important here.

to solve a system with 2 variables we need 2 equations. it cannot be solved with only 1 equation.
