Answer:
Given : ∠ABC is a right angle, ∠D BC is a straight angle.
To prove :∠AB D is a right angle.
Proof: ∠ ABC = 90°[ Given]
∠ D BC= 180° [ D BC is a straight line]
now, ∠ AB D and ∠ AB C are adjacent angles forming linear pair.
∠ AB D +∠ AB C =180° [By linear pair axiom]
⇒∠ AB D + 90= 180°
⇒∠ AB D=180°-90°
⇒∠ AB D=90°
∠AB D is a right angle
Hence proved.
Answer:
the length of the first side of the triangle is 
the length of the second side of the triangle is 
the length of the third side of the triangle is
Step-by-step explanation:
Let
x-----> the length of the first side of a triangle
y----> the length of the second side of a triangle
z---> the length of the third side of a triangle
we know that
-----> equation A

-----> equation B
The perimeter of the triangle is equal to


so
-----> equation C
substitute equation A and equation B in equation C

solve for x


Find the value of each side
the first side of a triangle is x

the second side of a triangle is y

the third side of a triangle is z
What do you want to solve for? Substitute in c to find F. To solve for C,
<span>F - 32 = 9/5(c) </span>
<span>C = 5/9(F - 32)</span>
At the standard 0.05 value, this is not significant, however at a 0.01 level, it would be significant
