Q9: The measure of ∠A is half the difference of the intercepted arcs.
.. (55 -12)/2 = 21.5

Q10: Tangents from the same point are congruent.
.. x +15 = 2x -5
.. 20 = x

Q7: The given congruences let you write two equations.
.. -x = y +8
.. -x = 3y +16
Equating the two equations for -x and solving for y gives
.. 3y +16 = y +8
.. 2y = -8
.. y = -4
.. -x = -4 +8 = 4
.. x = -4

Q8: The angle at the intersection is half the sum of the intercepted arcs. (Compare to Q9, where the intersection is external to the circle.)
.. 110 = (97 +x)/2
.. x = 220 -97 = 123

Write a rule for the nth term of the sequence. Then find a20. Assume the first termis a₁. 86, 79, 72, 65…
hodyreva [135]

Answer:

an = a(n-1) - 7

Step-by-step explanation:

the second term is smaller than the first term 7.

a20 = a19 - 7

a19 = a18 - 7

=> a20 = (a18 - 7) - 7

Then you can accumalate until a1

-> a20 = a1 - 19*7 = 86 - 19*7 = -47

How do I find the slope of the line?
charle [14.2K]

Answer:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second
navik [9.2K]

Answer:

6m

Step-by-step explanation:

the side of first square = 3 m

area of first square = 3^2= 9 m^2

let the side of second square = x m

since diagonal of first square = x m as per the question

in a square each angle is 90 degree

therefore by applying pythagorus theorem ,

diagonal ^2 = side^2 + side ^2

diagonal^2 = 3^2+3^2=9+9

DIAGONAL= square root of 18

diagonal= 3\sqrt{2} m = side of second square

therefore in second square ,

one angle is 90  degree , therefore by applying pythagorue theorem

diaqonal^2 = side ^2 + side ^2 = (3\sqrt{2})^2 + ( 3\sqrt{2})^2

diagonal ^2 = 18 + 18

diagonal = square root of 36

therefore diagonal of second square is 6m

hope it helps you... please mark me as the brainliest..
