We can use the cosine rule to find the third side:
c² = a² + b² -2abcos(C)
c = √(42² + 35² - 2(42)(35)cos(120)
c = 66.78
The answer is D.
<em>Greetings from Brasil...</em>
G = {4; 8; 12; 16; 20; 24; 28; 32; 36; 40; 44; 48; 52; 56; 60; 64; 68; 72; 76; 80; 84; 88; 92; 96; 100; 104; ...}
F = {1; 4; 9; 16; 25; 36; 49; 64; 81; 100; ...}
So, according to the statement, it is desired:
G ∩ F - the intersection between the 2 sets, that is, which numbers are present simultaneously in the 2 sets....
Looking at the sets we conclude that
<h2>G ∩ F = {4; 16; 36; 64; 100}</h2><h2 /><h2 />
<em>OBS: note that in truth G are the multiples of 4</em>
Answer:
51
Step-by-step explanation:
75 - 67 = 8
67 - 59 = 8
The difference between terms is 8
To find the next term take 59 -8
59-8 = 51
Check 51 -8 = 43 so we are correct
Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
