Answer:
<h2>x = 23.5</h2>
Step-by-step explanation:
It's the trapezoid.
We know: the sum of the angle measures at one leg of a trapezoid is 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 15.5 from both sides</em>
<em>divide both sides by 7</em>
Y=4/3 because if 3 goes to rhs is becomes divided by the number on the rhs so answer is 4/3
Answer:
x2 - 4x - 21
Step-by-step explanation:
Area = (x -7 )(x +3)
= x*x - 7*x + x*3 - 7*3
=x2 - 4x - 21
- two consecutive integers
<u>-4 and -3</u>
Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean theorem, a^2 + b^2 = c^2.
a = 11
c = 20
11^2 + b^2 = 20^2
121 + b^2 = 400
b^2 = 279
b = sqrt(279) = 16.7
