Answer:
Answer is 27, 32, 45
Step-by-step explanation:
In the right angle triangle, hypontenous is the longest side.
∴ In each option square of longest side has to be equal to the sum of square of other two side.
We know, ( as per pythogorean theorem)
If we check the last option; 27, 32, 45
In the given set of integer, we have longest side as 45
∴ conisdering 45 as hyptenous
Subtituting the value in the formula
⇒
⇒
⇒
∴
Hence, the set of given integer is not a pythagorean triple and are not side length of right angle.
<u>Given</u>:
Let A denote the angle of the given triangle which measures ∠A = 81°
Let B denote the angle which measures ∠B = 40°
The length of the side a = x.
The length of the side b = 7 cm.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the law of sine formula.
Applying the law of sine, we have;
Substituting the values, we have;
Simplifying, we get;
Cross multiplying, we have;
Thus, the length of the side x is 10.8 cm.
