The sum of the three angles of a triangle is always 180°. Tha is
(first measure) + (second measure) + (third measure) = 180°
Subtract the first two terms of this equation and you have
(third measure) = 180° - (first measure) - (second measure)
a. third measure = 180° - 45° - 55° = 80°
b. third measure = 180° - 50° - 40° = 90°
c. third measure = 180° - 110° - 35° = 35°
Answer:
Step-by-step explanation:
This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:
Therefore, the value of x is 11.
You can double-check using the sine ratio:
Insert the values:
Insert the equation into a calculator:
:Done
*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.
