The value of side z will be equal to 99.32 cm.
<h3>What is trigonometry?</h3>
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle are termed trigonometry.
Given that:-
In ΔXYZ, x = 27 cm, y = 79 cm and ∠Z=142°
So by applying the formula given below:-
z² = x² + y² - 2xyCos(142)
z² = 79² + 27² - 2 ( 79 x 27 x Cos142 )
z = 99.32 cm
Hence the value of side z will be equal to 99.32 cm.

Use the FOIL method to solve.
(3 + 4i)(3 - 4i)
(3 * 3) + (3 * -4i) + (4i * 3) + (4i * -4i)
9 - 12i + 12i - 16i
9 - 16i

Answer:
Step-by-step explanation:
(10 - x^2)/b = b/2
Cross multiply
2(10 - x^2) = b^2
20 - 2x^2 = b^2
2x^2 = 20 - b^2
Dividing through by 2
x^2 = (20 - b^2)/2
√x^2 = √(20 - b^2)/2
x = √(20 - b^2)/2
Answer:
