Answer:
x= 2
Step-by-step explanation:
Answer:
8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal
Step-by-step explanation:
For question 8:
Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.
For question 9:
By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165
For question 6/7:
We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.
Answer:
Its add 5. keep adding 5 to the answer to make the sequence
Step-by-step explanation:
The sequence is add 5 so next number is 8, +5, +5, +5
Answer:
8:9
Step-by-step explanation: Add 88+11 to get his weight before=99 Pounds. Then you put together the ratio. 88:99.
The GCF for those numbers would be 11, so divide them both by 11, to get a final answer of 8:9
Answer:
The real answer is 6
Step-by-step explanation:
Fairly simple. You know the length and the area, but you don't know the width. So your equation looks like this: 30 x ? = 180. But to figure out the width, you change the position of the numbers in the equation like this:
180 ÷ 30 = ?. Then you solve. 180 ÷ 30 = 6. If you want to double check your answer, you can plug in your answer to your original equation, 30 x 6 = 180.
Hope this helps!
