4
Step-by-step explanation:
Answer:
72 degrees
Step-by-step explanation:
let the ratio be 2x and 3x
2x + 3x =180° ( co interior angles )
5x = 180°
x = 180 ÷ 5
x = 36°
And the smaller angle = 2 × 36° = 72°
Answer:
x=9
Step-by-step explanation:
m5=m1 so
25=3x+7
18=3x
x=9
Answer:
there are two terms which means it is a binomial algebraic expression
Step-by-step explanation:
the first term is -9
and the second term is 5.5
note:be aware that the negative sign is there in the first term and the reason that we didn't put the negative sign in the second is because there is no negative sign before 5.5 .
Answer:
6
Step-by-step explanation:
8x + 2 + 70 + 60 = 180 ( sum of all angles of a triangle = 180 degree )
8x + 132 = 180
8x = 180 - 132
8x = 48
x = 48 / 8
x = 6
Therefore 3 rd option is correct.
