Complete Question
In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.
Answer:
499.9cm
Step-by-step explanation:
We solve for length x using the Sine rule
w/ sin W = x /sin X
Cross Multiply
x × sin W = w × sin X
x = w × sin X/ sin W
x = 780 × sin 21°/ sin 146°
x = 499.88 cm
Approximately to nearest tenth = 499.9cm
Answer:
8 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , that is
exterior angle + 135° = 180° ( subtract 135° from both sides )
exterior angle = 45°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular then number of sides n is
n = 360° ÷ 45÷ = 8
$21.80 because you will do 20% over 100% = x over $26. Than you will do 26 times 20 divided by 100, and you get 5.2, than you will do 26-5.2 and you get $21.80
