Answer:
a.![x=10 \textdegree](https://tex.z-dn.net/?f=x%3D10%20%5Ctextdegree)
b.
![m\angle L=39\textdegree\\\\m\angle M=51\textdegree\\\\m\angle K=90\textdegree](https://tex.z-dn.net/?f=m%5Cangle%20L%3D39%5Ctextdegree%5C%5C%5C%5Cm%5Cangle%20M%3D51%5Ctextdegree%5C%5C%5C%5Cm%5Cangle%20K%3D90%5Ctextdegree)
Step-by-step explanation:
a. We know that angles in a triangle add up to 180°.
-The right angle triangle in the right triangle has a measure of 90°.
We can therefore equate our angles to 180° and solve for x;
![180=\perp\angle+(2x+19)+(3x+21)\\\\180=90+(2x+19)+(3x+21)\\\\90=5x+40\\\\5x=50\\\\x=10\textdegree](https://tex.z-dn.net/?f=180%3D%5Cperp%5Cangle%2B%282x%2B19%29%2B%283x%2B21%29%5C%5C%5C%5C180%3D90%2B%282x%2B19%29%2B%283x%2B21%29%5C%5C%5C%5C90%3D5x%2B40%5C%5C%5C%5C5x%3D50%5C%5C%5C%5Cx%3D10%5Ctextdegree)
Hence, the angle measure is x=10°
b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:
![m\angle L=(2x+19)\textdegree\\\\=(2\times 10+19)\textdegree\\\\=39\textdegree\\\\m\angle M=(3x+21)\textdegree\\\\=(3\times 10+21)\textdegree\\\\=51\textdegree](https://tex.z-dn.net/?f=m%5Cangle%20L%3D%282x%2B19%29%5Ctextdegree%5C%5C%5C%5C%3D%282%5Ctimes%2010%2B19%29%5Ctextdegree%5C%5C%5C%5C%3D39%5Ctextdegree%5C%5C%5C%5Cm%5Cangle%20M%3D%283x%2B21%29%5Ctextdegree%5C%5C%5C%5C%3D%283%5Ctimes%2010%2B21%29%5Ctextdegree%5C%5C%5C%5C%3D51%5Ctextdegree)
Since, the m∠K is a right angle, it measures 90°
Answer:
here p=0.65 and n=100 hence standard error =(p*(1-.
