12/7. You put the numbers into mixed numbers giving you 18/7 and 9/6. For division you flip the second fraction and multiply them together. So you do 18/7 x 6/9. You're also able to cross cancel 18 and 9 giving you 2/7 x 6/1. 6 x 2 is 12 and 7 x 1 is 7. Your answer is 12/7.
<span>Congruence between two triangles means six items, all three sides and all three angles, are congruent. Thus the statement ABC DEF has a very precise meaning. It succinctly summarizes the six statements (assume lines atop these segments): ABDE, BCEF, ACDF, AD, BE, and CF. It is very important to maintain the vertices in the proper order. Not doing so is a common mistake.</span>

You have to move the decimal point all the way to behind the 9.
You move it eleven places to the right.
The answer is
9.3 x 10^-11
Answer:
the correct answer is 77°
Step-by-step explanation:
Angle GHJ and IHJ form supplementary angles which add up to 180°
therefore angle IHJ=180-154
angle IHJ=26°
Triangle IHJ is an isosceles triangle whose base angles HIJand IJH are equal. Lets assign them the same value, x° each
since the sum of all interior angles of a triangle add up to 180°, then x°+x°+26°=180°
2x+26=180
2x=154°
x=77°
Therefore both HIJ and IJH measure 77°
