Answer:
x = 20
Step-by-step explanation:
since the triangle is a right angle, that means the angle is 90 degrees
equation:
30 + 3x = 90
subtract 30 on both sides
30 - 30 + 3x = 90 - 30
3x = 60
then divide each side by 3

x = 20
Yes it isssss !!!!!!!!!!!!!
Answer:
Length is 14 in
Width is 8 in
Step-by-step explanation:
<u>Given:</u>
- Length = l
- Width = w
- Perimeter = P = 44 in
<h3>Solution</h3>
<u>Equations as per given:</u>
- l - w = 6
- P= 2(l+w) = 44 ⇒ l +w = 22
<u>Adding up the two equations:</u>
- l - w + l +w = 6 + 22
- 2l = 28
- l = 28/2
- l = 14 in
<u>Then finding the value of w:</u>
- w = l -6
- w = 14 - 6
- w = 8 in
<u>Answer:</u> The length of the rectangle is 14 inches and width is 8 inches
