To solve the problem, we need to use the relation between the angles to find a relation involving x. Then we need to solve for x and use that value to determine the measure of the desired angle.

The diagram shows you ...

... ∠KIJ + ∠JIH = ∠KIH

The problem statement tells you ∠KIJ = ∠JIH, so we can substitute ∠JIH in the above equation to get

... ∠JIH + ∠JIH = ∠KIH

... (4x+3) + (4x+3) = (12x)

... 8x +6 = 12x

... 6 = 4x . . . . . . . subtract 8x

Since we want to know the value of 12x, we can go directly there

... 18 = 12x . . . . . . multiply the above equation by 3

m∠KIH = 18°

Parallel, orthogonal, or neither.
zzz [600]
Vectors are orthogonal, when dot product u\cdot v=0

u\cdot v=\langle-1,3\rangle\cdot\langle-9,-3\rangle=(-1)\cdot(-9)+3\cdot(-3)=9-9=0

Vectors u and v are orthogonal.

If cheese is $4.40 per kilogramme, what should I pay for 200 grammes?
Verizon [17]
1 kg is 1,000 grams.


200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.

Thus 200 g= 1/5 kg = 0.2 kg.



      1 kg of cheese is $4.40,

so 0.2 kg of cheese is 0.2kg x $4.40/1kg=4.40 x 0.2 $= 0.88$


Answer: $0.88
