Angle 1 and angle 2 are complementary angles. The measure of angle 1 is 30 degrees. The measure of angle 2 is 4x degrees. Find the value of x.

x=15

Step-by-step explanation:

Complementary angles add to 90 degrees

<1 + <2 = 90

30 + 4x = 90

Subtract 30 from each side

30-30 +4x = 90-30

4x = 60

Divide each side by 4

4x/4 = 60/4

x = 15

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 : )
