U should have subtract 180 and 131
Answer:
30 years old
Step-by-step explanation:
5x = x + 2(12)
5x = x + 24
4x = 24
x = 6
5(x)
5(6) = 30
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
Answer:
3
Step-by-step explanation:
7.50 + 6.25x=26.25
6.25x=26.25-7.50
6.25x=18.75
x=3
