Solve for X and solve for Y please help me

Answers

Answer 1

Answer:

69°+72°=141°

180°-141°=39°

x=39°

180°-69°=111°

111°+27°=138°

180°-111°=69°

y=69°

Answer 2

To find x:
You must know that the sum of angles in triangle =180 so
69+72+x=180
X=39
For y (you need to know 2angles to find it )
So
180-69=111
111+27+y=180
y=42

(iv) The area of a rectangle with breadth
5 cm is 30 sq. cm. Find its length and
perimeter.

Answers

Answer:

Step-by-step explanation:

if the breadth is 5cm, then you divide 30/5 to get your length since it's length times breadth to get the area, so 6cm for the length

and then it's 2b plus 2l to get your perimeter so

2(5)+2(6)=p

10 plus 12 equals p

22 is your perimeter, 6 is your length

The length of a rectangle is 2 ft longer than its width.
If the perimeter of the rectangle is 40 ft, find its area.

Answers

Answer: yes

Step-by-step explanation:

set the length=2 + w
and the width=w

P = 2l + 2w
40 = 2(2+w) + 2(w)
40 = 4 + 2w + 2w
36 = 4w
w = 9

therefore length=2+w=2+9=11
and width=w=9

Area = length x width
A = 11 x 9 = 99
