In triangle ABC:
∠1 = 90°
According to the angle sum property:
∠1 + ∠2 + ∠3 = 180
Since angle 1 is 90 degrees
∠2 + ∠3 = 180 - 90
∠2 + ∠3 = 90° [∠1 + ∠2 + ∠3 = 180]
Answer:
Correct answer is option A. T
Step-by-step explanation:
Given that
In a
, RS = 7, RT = 10, and ST = 8.
To find:
Smallest angle = ?
Solution:
We can use cosine rule here to find the angle.
Formula for cosine rule:

Where
a is the side opposite to 
b is the side opposite to 
c is the side opposite to 
Using the cosine rule:

Now, let us use Sine rule to find other angles:



Smallest angle is 
Correct answer is option A. T
-8/2. eight and two thirds times 30 is 260, and seven percent of 270 is 91/5, and subtracted by 10 is -8.2
Hello!
The area of a parallelogram is A=bh.
A=9(5)=45
Each tile has an area of 45. Now we multiply by 12 to get the total.
45(12)=540
The total area of all the tiles is 540 in.²
I hope this helps!
