Question

Need to know how to solve, and I have others I need help with. Please someone help!

Answer 1

Looking at the diagram, Each division is 90 degrees. We can see the 90 degrees symbol there. Therefore,

`17x\text{ + 7 + 9x + 5 = 90}`

`17x\text{ + 9x = 90 - 7 - 5}`
`26x\text{ = 78}`
`x\text{ = 78/26 = 3}`

Also, vertically opposite angles are equal.

Therefore,

`y\text{ = 17x + 7}`

Substituting x = 3 into the above equation,

`y\text{ = (17 }*3)+7=58\text{ degrees}`
