The first five are 1, 2, 3, 4, and 5
Answer:
x=30° y=110°
Step-by-step explanation:
80+70=150
180-150=30° 》》》》 angles in a triangle add up to 180°
x=30° opposite angles are equal
180-140=40° angles on a straight line add up to 180°
30+ 40=70
180-70=110°
y=110°

Answer:
Step-by-step explanation:
subtract m from both sides and you get - 3/4m
divide 2/3 divided by -3/4
-8/9
Answer:
Below in bold.
Step-by-step explanation:
This is a regular polygon so all sides are congruent, therefore:
The perimeter of the polygon = 6*34 = 204 units.
We can divide the polygon into 6 conguent triangle with height 30 and base 34.
So area of 1 triangle = 1/2*34*30 = 510.
So area of the polygon = 6 * 510 = 3060 unit^2.
Perimeter of the polygon = 6*34 = 204 units.
