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°

What are questions 10-15?

AfilCa [17]

Answer:

10. 105

11. 75

12. 75

13. 105

14. 75

15. 105

Step-by-step explanation:

Notice that 75? Anything that is adjacent (has a common vertex like 75º) to the vertex is a linear pair. here is an example below:

Since there is only THAT 75, you must find the supplementary angle (adds up to 180). and remember in order to get a supplementary angle it has to be a STRAIGHT LINE and HAS TO EQUAL 180. (4, 1 in your image)

180 - 75 = 105.

and also it's also a linear pair so it reflects too which makes things a lot easier!

So, if 4 is 75 and it reflects, then that means 2 is also 75. 1 is 105 and it reflects so 3 has to be 105. and the same for the rest of the numbers.

Hope this makes sense
