If m∠UNR = 180° find m∠RNS A. 27° B. 34° C. 59° D. 94°

LenaWriter [7]

Answer:

Option A) m∠RNS=27°

Step-by-step explanation:

We know that $m$ ∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:

$m$ ∠RNS = $(3x+6)^{o}$

$m$ ∠SNT= $(13x+3)^{o}$

$m$ ∠TNU= $(10x-11)^{o}$

Now let us add all the angles and solve for the value of $x$ as follow:

$m_{RSN}+m_{SNT}+m_{TNU}=m_{UNR}\\\\(3x+6)+(13x+3)+(10x-11)=180\\\\3x+13x+10x+6+3-11=180\\\\26x-2=180\\\\26x=180+2\\\\26x=182\\\\$

$x=\frac{182}{26} \\\\x=7$

Now lets plug in the value into the expression for angle $m$ ∠RNS to find the angle as:

$RNS = (3x+6)^{o}\\\\RNS=(3(7)+6)^{o}\\\\RNS=(21+6)^{o}\\\\RNS=27^{o}$

Thus Option A. is the correct answer.

Pls answer

cluponka [151]

Answer:

$8.49\ units$

Step-by-step explanation:

we know that

The Pythagorean Theorem states that in a right triangle

$c^2=a^2+b^2$

where

c is the greater side (the hypotenuse)

a and b are the legs

In this problem

Let

c=AB ---> distance from point A to point B

a ---> the difference of the x-coordinates both points

b ---> the difference of the y-coordinates both points

$a=1-(-5)=6\ units\\b=6-0=6\ units$

substitute

$AB^2=6^2+6^2$

$AB^2=72$

$AB=\sqrt{72}\ units$

$AB=8.49\ units$
