Answer:
Part a) 
Part b) 
Step-by-step explanation:
step 1
Find the length side BC
Applying the law of sines
we know that

we have



substitute

solve for BC


step 2
Find the measure of angle B
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
so

substitute the given values




step 3
Find the length side AC
Applying the law of sines
we know that

we have



substitute

solve for AC


The Midpoint Formula works exactly the same way. If you need to find the point that is exactly halfway between two given points, just average the x-values and the y-values.
Hope this helps:)
Answer:
Explanation:
1) The two parallel sides of different legths 1\frac{3}{4}143 and 1\frac{1}{4}141 constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.
Answer:
The answer to your question is P = 17(π + 2) or 17π + 34
Step-by-step explanation:
Data
Diameter = 34 cm
Formula
P = rπ + 2r
Process
1.- Find the radius
radius = diameter / 2
radius = 34 / 2
radius = 17 cm
2.- Substitute the values in the formula
P = 17π + 2(17)
3.- Simplification
P = 17π + 34
4.- Factor
P = 17(π + 2)
