For the writing assignment, the number of ways of choosing from two essay topics three different mandatory lengths is given by:
![^2C_1 \times { ^3C_1}= 2\times3=6](https://tex.z-dn.net/?f=%20%5E2C_1%20%5Ctimes%20%7B%20%5E3C_1%7D%3D%202%5Ctimes3%3D6)

Step-by-step explanation:
Answer:
the answers are
m<1 = 65
m<2=25
m<3=115
Step-by-step explanation:
first of all in the triangle
the angles are 90, 25 and an unknown(let be x)
so,
triangle=sum of all sides
180=90+25+x
180-115=x
x=65
now,
to find m<2
m<2+65=90
m<2=25
then,
to find m<1,
m<1+m<2=90(sum of 2 opp interior angle equals the exterior angle)
or, m<1+25=90
m<1=65
again
for m<3,
180(straight line) +m<2 +m<3 =360(complete turn)
180+25+m<3=360
m<3 =360-205
m<3 =155
