They are both drawn as right angled triangles so if we can constract them then they should obey pythagoras theorem
First traingle:- 8^2 = 64
7^2 + 6^2 = 49 + 36 = 85 so this does not obey the theorem and you cant draw it.
Second traingle: 9^2 = 81 and 5^2 + 7^2 = 25 + 49 = 75 so we cant draw that one either.
By the geometric mean theorem,
So, by the Pythagorean theorem,
Answer:
We know that angles B and D/A and C are congruent, this is because all opposite angles within a parallelogram are congruent.
(6x+40) + (x) = 180
7x + 40 = 180
7x = 140
x = 20
The Value of X is 20.
The formula to find the volume of a rectangular solid is the first one.
V = lwh
Answer:
x = 15
y = 90
Step-by-step explanation:
Step 1: Find <em>x</em>
We use Definition of Supplementary Angles
9x + 3x = 180
12x = 180
x = 15
Step 2: Find <em>y</em>
All angles in a triangle add up to 180°
3(15) + 3(15) + y = 180
45 + 45 + y = 180
90 + y = 180
y = 90°
