Answer:

Step-by-step explanation:

Hypotenuse squared = one leg square plus the other leg squared.

H^2=L1^2+L2^2

L2^2=H^2-L1^2

L2^2=14^2-3^2

L2^2=196-9

L^2=187

L2=√187

L2=13.7

L2 is approximately equals to 14

Find the measure of M

Neporo4naja [7]

Answer:

∠M = 78º

∠N = 68º

∠P = 34º

Step-by-step explanation:

we know that the inside of a triangle is equal to 180º. we also know that angle p and angle q equal 180º when added together because that's the angle of a straight line. first we need to find angle p.

180 - 146 = 34º

now we can set it up so that all the angles equal 180º when added together.

(5y + 3) + (4y + 8) + 34 = 180

5y + 4y = 9y

9y + 3 + 8 + 34 = 180

3 + 8 + 34 = 45

9y + 45 = 180

-45 -45

-------------------

9y = 135

÷9 ÷9

y = 15

now we can plug 15 in for y

(5 x 15 + 3) = 78º

(4 x 15 + 8) = 68º

to double check, add all three angles and make sure they equal 180º

78 + 68 + 34 = 180

| -4 + 5\2 | - (-x) =-3

Leto [7]

Answer:

x = -4.5

Step-by-step explanation:

Solving the equation :

$\left\vert -4+\frac{5}{2} \right\vert -\left( -x\right) =-3$

$\Longleftrightarrow \left\vert \frac{-8}{2} +\frac{5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-8+5}{2} \right\vert +x =-3$

$\Longleftrightarrow \left\vert \frac{-3}{2} \right\vert +x =-3$

$\Longleftrightarrow \frac{3}{2} +x =-3$

$\Longleftrightarrow x =-3-\frac{3}{2}$

$\Longleftrightarrow x =-\frac{6}{2} -\frac{3}{2}$

$\Longleftrightarrow x = -(\frac{6}{2} +\frac{3}{2} )$

$\Longleftrightarrow x =-\frac{9}{2}$

$\Longleftrightarrow x =-4.5$

swat32

Answer:

8/13

Step-by-step explanation:

Step 1 : Write all the data

Total number of students = 26

Number of girls in class = 10

Number of boys in class = 26-10 = 16

Step 2 : Find the probability

Probability of pulling out a boy's name = number of boys in class

Total number of students in class

= 16/26

Simplify :

16/26 = 8/13
