Answer:
39.9
Step-by-step explanation:
a/sinA = c/sinC
a/sin(77) = 16/sin(23)
a = sin(77) × 16/sin(23)
a = 39.89935764
Answer:
The measure of other three angles are 135° , 45° and 45°
Step-by-step explanation:
The opposite angles of a parallelogram are equal.
So if we consider a parallelogram ABCD ,
Angle A = Angle C
Angle B = Angle D
If we take angle A = 135° then angle C = 135°
SUM OF INTERIOR ANGLES OF A QUADRILATERAL IS 360°.
A+B+C+D=360°
135°+B+135°+D=360°
270°+B+D=360°
But B=D
So,2B=90°
B=45°
D=45°
So A = C = 135°
A = C = 135° B = D = 45°
A = C = 135° B = D = 45°

Answer:
62.8 in2
Step-by-step explanation:
With round pizza we need to
find the area of each pizza in
square inches, then determine
the difference.
The area of a circle is given by:
A = πr2
12 inch diameter, radius = 6
a = π(62) = 36π in2
8 inch diameter, radius = 4
a = π(42) = 16π in2
Difference: 36π - 16π = 20π in2
using 3.14 for pi, the difference is
20(3.14) = 62.8 in2
