Answer:
tan C = 1/2
Step-by-step explanation:
The tan function in a right triangle is the opposite side over the adjacent side
tan C = 11/22
We can divide the top and bottom by 11
tan C = 1/2
Finish the equation given for x:
10x +15 = 9(9)
= 10x +15 = 81
Subtract 15 from both sides:
10x = 66
Divide both sides by 10:
x = 66/10
X = 6.6
Now replace x with 6.6 in the equation for DE:
DE = 2(6.6) +3
Simplify:
DE = 13.2 + 3
DE = 16.2
Answer:
42 degrees
Step-by-step explanation:
Complimentary angles are two angles whose total is equal to 90 degrees. Since we already know that Angle N measures at 48 degrees, all we have to do is subtract that from 90 degrees to find the measure of Angle I.
90 - 48 = 42
So, the measure of Angle I is 42 degrees! It's pretty easy finding complementary angles once you know how to. I hope this helps! Have a lovely day!! :)
