Answer:
a = 30 degrees; b = 60 degrees; and c = 105 degrees.
Step-by-step explanation:
Angle a and the 30 degree angle are vertical angles and thus are equal.
Since the interior angles of a triangle always add up to 180 degrees, 30 + b + 90 degrees = 180 degrees, so that b must be 60 degrees.
Angle c and the 75 degree angle are straight angles, and so their sum must be 180 degrees. Thus, c = 105 degrees.
This one should have come before the other one. We apply the cone formula
The metric system originated in France in 1799 following the French Revolution although decimal units had been used in many other countries and cultures previously. Although there have been many different measurements and the definitions of the units have been revised, the official system of measurements of most countries is the modern form of the metric system which is known as the "International System of Units".
Answer:
7cm
Step-by-step explanation:
Area = Length x width
A = 35
w= L - 2
L = w+ 2
Now it becomes
35 = ( w+2) x w
35 = w^2 + 2w
W^2 + 2w - 35 = 0
By Factorization we have
( w + 7)( w-5)
w = 5cm
Since L = w + 2, we have
L = 5 + 2
= 7cm
Answer:
Step-by-step explanation:
Area = 35*100*2 + 50*100*2 + 50*35*2
= 7000 + 10000 + 3500
= 20500 cm2
