Find the measures:
a. MZR =
b. XY
C. m X
d. ms

a. 75

b. 6

c. 55

d. 50

Step-by-step explanation:

for b. XY = QR

for c. <X = <Q

for d. <S = <Z

for a. <R = <Y ...  we know <s Q and S are 55 and 50. The triangle sum has to = 180. So 50+55=105 180-105=75  so <R = 75

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
