Find the missing side lengths, put radicals in the simplest form

Mathematics
1 answer:
Dominik [7]3 years ago
3 0

Answer:

u = 2\sqrt{5}     v = \sqrt{15}

Step-by-step explanation:

longer leg of a 30-60-90 triangle is shorter leg times \sqrt{3} and the hypotenuse  of a 30-60-90 triangle is shorter leg times 2.

So, the length of the shorter leg = \sqrt{5}

Therefore, u = 2\sqrt{5}  and v = \sqrt{3} \sqrt{5}  = \sqrt{15}

25m + 100 - 24m - 75 = 68.
Maksim231197 [3]

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

Which place is the tenths and what is it rounded to? please answer quick thx​
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

see attached to identify which is the tenth's place

How you round the tenth's place depends on the digit in the hundredths place.

If the hundredths digit is less than 5, then you keep the tenths place the same (i.e round down)

If the hundredths digit is greater or equal than 5, then you increase the tenths place by 1 (i.e round up)

Question 3.<br> X and Y are<br> supplementary angles. Given X=72°, find the value of Y.
Natalija [7]

Answer:

<h2>Y = 108°</h2>

Step-by-step explanation:

Since X and Y are supplementary angles it means that the sum of their angles add up to 180°

To find Y , add X and Y and equate it to 180° and solve

That's

X + Y = 180

Y = 180 - X

X = 72°

Y = 180 - 72

We have the final answer as

<h3>Y = 108°</h3>

Hope this helps you
