Answer:
59°
Step-by-step explanation:
The angles of a triangle equal 180°.
Also the angle of a straight line is 180°.
So you first find the missing bottom angle by taking 180-147 to equal 33.
Then you take 33+88+x=180
solve for x by subtracting 88 and 33 from 180 to equal 59.
Answer:
180
Step-by-step explanation:
k = 3
v = 60
(Found v by dividing any of the top numbers by the bottom number, ex: 420/7 = 60)
3k = 3(60)
3k = 180
The perimeter of a rectangle is (2 lengths) plus (2 widths).
If one side is missing, then it sounds like you still have enough information
to know what the length and the width are. Just take each number and use
the first line up there /\ to calculate the perimeter with them.
