Perimeter=2L+2W, in this case L=80+2(25) and W=170+2(25) so
P=2(L+W)=2(80+50+170+50)
P=2(350)=700m
$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies
We do this by dividing 360°<span> by the number of sides, which is 8. (b) Calculate the size of each interior angle in the regular octagon. We do this by subtracting the size of each exterior angle, which is 45°, from </span>180°<span>. A regular polygon has equal exterior angles of 72°</span>
Answer:
Triangle ITA is the answer.
Step-by-step explanation:
<S = <I means that the triangle IRS is an isoscles.
The midpoint (T) cutting both congruent side length sides at the same angle means that Line TG and Line TA are equal.
Also T being the midpoint means Line TI = Line TS.
Given that angles <G and <A are same.
You can use SSA (side-side-angle) to prove triangles are congruent so line SG is equal to Line IA.
