Pythagorean Theorem: A^2 + B^2 = C^2
<span>We know A and C, let's find B by doing it backwards </span>
<span>C^2 - A^2 = B^2 </span>
<span>4^2 - 7 (square root of 7 squared is just 7) = B^2 </span>
<span>16 - 7 = B^2 </span>
<span>9 = B^2 </span>
Answer:
25 miles/hour
Step-by-step explanation:
If you were to divide 125 by 5, you would get 25 miles per each hour as your answer. Brainless if I am correct.
Answer:
∠ 1 = 50°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum the 4 angles of the polygon and equate to 540°
let the unknown interior angle be x
x + 100° + 120° + 100° + 90° = 540° , that is
x + 410° = 130°
∠ 1 and x are adjacent angles on a straight line and sum to 180° , so
∠ 1 = 180° - 130° = 50°
ANSWER
EXPLANATION
The given line passes through (1,4) and (3,-4).
The slope of this line is calculated using the formula:
We substitute the points into the slope formula to get:
We substitute the first point and slope into the point-slope formula
This implies that
We expand to get
