Answer:
x=13
Step-by-step explanation:
14x-2=180
+2 +2
14x=182
/14 /14
x=13
Answer:
Correct option is the third option:
6*3 - 4+3^2
We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Step-by-step explanation:
but ... you had already correctly answered the first part.
L² + W² = d²
Pythagoras ...
all you needed to do now was do the calculations. no "brainware" needed ...
30² + 10² = d²
900 + 100 = d²
1000 = d²
d = 31.6227766... ≈ 31.6 units
