Answer:
W = 7 - x
Step-by-step explanation:
The perimeter is P= 2L + 2×W , where L is the length and W is the width.
If L = (x+2) , replacing L with the expression x+2 we have
P= 2×(X+2) + 2W ⇔ 18 = 2x + 4 + 2W ⇔ 2W =18 - 2x - 4 ⇔ 2W = 14 - 2x
⇔ W = 7 - x
Answer:
x = 11
Step-by-step explanation:
interior angles of a triangle = 180
equation:
⇒ 82 + 31 + 6x + 1 = 180
combine like terms:
⇒ 82 + 31 + 6x + 1 = 180
⇒ 114 + 6x = 180
subtract 114 on both sides:
⇒ 114 - 114 + 6x = 180 - 114
⇒ 6x = 66
divide 6 on both sides:
⇒ 6x = 66
⇒ 
⇒ x = 11
0.0075 ÷ (1.5 x 10^-6) = (7.5 x 10^-3) ÷ (1.5 x 10^-6) = (7.5 ÷ 1.5) x (10^(-3 - (-6))) = 5 x 10^(-3 + 6) = 5 x 10^3
This type of triangle is a right triangle which has two other acute angles which are equal to one another. This is because 45 is complementary to itself.
