If chord xy is congruent to chord yz. what is the measure of yoz?

Option B. 36°

Step-by-step explanation:

we have that

XY≅YZ

we know that

OX=OY=OZ=radius of the circle

therefore

Triangle OXY is congruent with triangle OYX

Remember that

If two figures are congruent, then its corresponding sides and corresponding angles are congruent

so

m∠YOZ=m∠XOY

we have

m∠XOY=36°

therefore

m∠YOZ=36°

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
