Use the image to answer questions 6-7.
zepelin [54]

Answer:

x = 22

y = 24

Step-by-step explanation:

110 and 5x are equal to each other because they are vertically opposite of each other.

110 = 5x; divide 5 on both side; x = 22

a line is 180 degrees, so if we use angle 110 with 3y-2, then 3y-2 must equal 70 (180 - 110).

70 = 3y - 2; add 2 to both sides

72 = 3y; divide 3 on both sides; x =24

??? I only know how to find the complementary angles<br> :/
scoundrel [369]
Well to find the angles, simply see what must the angles be, to equal to 180 or 90 degrees. So we know the angle between C and D would be 90 degrees, so will the angle between A and C. The angle between B and A and the angle between B and C must give us a total of 90 degrees, so that means each would be 45 degrees. As 45 + 45 = 90. Also I would assume that angle between D and F would also be the same as between B and A which would be 45 degrees. Finally the angle between A and F would be the difference between 180 and 45 degrees. So it would be 180 - 45 = 135 degrees.

The lesson is 19.2 Angles in inscribed Quadrilaterals
alexdok [17]

Answer:

m<R=44.9,m<S=56.9,m<T=44.9,m<U= 32.9.

Step-by-step explanation:

When two chords are equal then the measure of the arcs are equal.

Chord RU= Chord UT

Or , m arc RU= m arc UT,

3z-4=x+2z+7   Or             z=x+11

Chord RS=Chord ST ,

m arc RS=m arc ST=3x+5

Sum of m arc in a circle =360 degrees.

Or ,

3x+5+3x+5+3z-4+x+2z+7=360

7x+5z+13=360

Substituting z=x+11

7x+5(x+11)+13=360

7x+5x+55+13=360

12x+68=360

12x=292,x=24.3

z=x+11=11+24.3=34.3

m arc RU=marc UT= 3z-4=3(24.3)-4=69

m arc RS =marc ST= 3x+5=3(24..3)+5=77.9

m<R= (marc UT+ m  arc ST)÷2

m<R=(69+77.9)÷2=73.45

m<S= (m arc RU+m arc UT)÷2

m<S= (69+69)÷2=69

m<T=(m arc RU+m arc RS)÷2=73.45

m<U=(m arc RS+m arc m arc ST)÷2=77.9
