The three angles must add to 180. So x=180-(50+90)= 40 degrees.
Answer: option C
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo. The triangle is a right angle triangle ABC
Assuming the given angle is #,
Recalling the trigonometric ratio,
tan # = opposite / adjacent
If tan # = 4, it means
opposite / adjacent = 4/1
Therefore, opposite = 4 and adjacent = 1
Applying Pythagoras theorem,
Hypotenuse^2 = opposite ^2 + adjacent ^2
Hypotenuse = AC
Opposite = 4
Adjacent = 1
AC^2 = 4^2 + 1^2 = 17
AC = ± √17
To determine cos #, we would apply another trigonometric ratio,
Cos# = adjacent /hypotenuse
Cos# = 1/±√17
Cos # =-1 /√17 or 1/√17
Answer:
B -9<x-4 <9
Step-by-step explanation:
|x-4|<9 ➡ -9 < x-4 < 9
-5 <x <13
I assume you mean a triangle where the sides dont connect if so, than 2, 2, and 10 is a pretty good bet.
Answer:
48
Step-by-step explanation:
2 = 2 line 1
2 + 4 = 6 line 2
2 + 4 + 6 = 12 line 3
The next line we would add 12 since we are adding the sum of the previous line
2 + 4 + 6 +12 = 24 line 4
The next line we would add 24 since we are adding the sum of the previous line
2 + 4 + 6 +12+24 = 48 line 5
