Answer:
12, The answer is 12
Step-by-step explanation:
you are just counting by multiples of 3
3, 6, 9, 12, 15
so all angles of a triangle are going to add up to 180°
<u>so for L</u>
20 + 72 + x = 180
92 + x = 180
180 - 92 = 88
<u>For I</u>
56 + 89 + x = 180
180 - 145 = 35
<u>For C</u>
28 + 128 + x = 180
180 - 156 = 24
<u>For D</u>
122 + 38 + x = 180
180 - 160 = 20
Answer:
8n-23
Step-by-step explanation:
a=-15 and d=8
so nth term=-15+(n-1)8
=8n-23

Here's the solution ~
Let's find the measure of hypotenuse first, by using Pythagoras theorem ;





Now, let's find the asked values ~



For Cos y :



As we can see that both sin x and Cos y have equal values, therefore The required relationships is equality.
I.e Sin x = Cos y
Hope it helps ~
