Answer:
18.0 cm to 1 decimal point.
Step-by-step explanation:
First work out the unknown side (s) of the right triangle using the Pythagoras theorem:
s^2 = 13^2 - 5^2
= 169 - 25 = 144
s = sqrt 144 = 12 cm.
Now consider the other triangle:
s = 12
The missing angle = 180 - 65 - 40 = 75 degrees.
By the Sine Rule:
x / sin 75 = 12 / sin40
x = 12 sin 75 / sin 40
= 18.03

Answer:
2 or 4
Step-by-step explanation:
Okay first you must solve for A and B. Then X and Y. Then solve the rest liek 2 and 4.
2469173 will be in each box. 2 will be leftover. i put this up BEFORE.
<h3>Since the only two other options are quadratic and given that it must satisfy one of them i will assume the following general form of the function.</h3>
<h3>Substitute in the first function any point.</h3>
<h3>I'm pretty sure something is wrong with the given</h3>
