This is pre calculus please help !Describe three ways to determine the measure of segment YZ.

Dmitry [639]

(1) Using trigonometric ratios:
$sin(30) = \frac{YZ}{50}$
$YZ = 25$

(2) Using Pythagoras' Theorem:
$cos(30) = \frac{XY}{50}$
$50cos(30) = XY$
$50^{2} - 50^{2}cos^{2}(30) = YZ^{2}$
$2500 - 2500cos^{2}(30) = YZ^{2}$
$YZ = 25$

(3) Using sine rule:
$\frac{50}{sin(90)} = \frac{YZ}{sin(30)}$
$50 = \frac{YZ}{sin(30)}$
$50sin(30) = YZ$
$YZ = 25$

Answer:

4, 343

Step-by-step explanation:

numerator: 6-2=4; (4^2)^2=4^4;

denominator: 3+1=4; 4^3

thus, 4^4/4^3=4

numerator: (14-7)^9=7^9

denominator: ((3+4)^3)^2=(7^3)^2=7^6

thus, 7^9/7^6=7^(9-6)=7^3=343
