It would be A. You can find this out by using SOH CAH TOA,

SOH means sin= opposite/hypotenuse

CAH mean cos= adjacent/hypotenuse

TOA means tangent= opposite/adjacent

You would use CAH since you are trying to find cos∠C

You would have cos∠C=10/26.

26 is the hypotenuse since it is opposite the right angle and is the biggest side.

10 is the adjacent since it is right next to C

You would simplify this down to 5/13 by dividing by 2.

This gives you A.

Please be quick i dont have that much time
Oduvanchick [21]

Answer:

To find the sum of interior angles in a polygon, we can use the formula:

180(n-2) where n is the number of sides.

Since this is pentagon (5 sides), then 180(5-2)=180*3=540

The missing angle would then be

540-97-111-104-115=113

Since angles on a straight line add up to 180, then

x+113=180

x=67

The ratio of the same side angles of two parallel lines is 1:14. Find all angles.
Oksanka [162]
The angles that lie at the same side of parallel lines are known to be always supplement of each other. This means that when we add them together, the value is 180°. If we let x be the common factor for the measures of the angle, the equation that we could use to determine the answer is,
 
                x + 14x = 180°

The value of x from the equation is 12. Hence, the angles are,
       
              x = 12
            14(12) = 168

Answer: 12° and 168°

What is the percentage of the change from 6 to3?
luda_lava [24]

Answer:

The percentage of the change from 6 to 3 is a 50% decrease.

Step-by-step explanation:

Given the number '6'.

If the number changes from '6' to '3', means the number reduces to half.

as 6/2 = 3

Thus,

6  → 100%

and when reduces to half

3  → 50%

Thus, the percentage of the change from 6 to 3 is a 50% decrease.

ANOTHER METHOD

% Decrease = (original value - new value) / original value × 100%

                    = (6 - 3) / 6 × 100%

                     = 3/6 × 100%

                     = 0.5 × 100%

                      = 50%

Thus, the percentage of the change from 6 to 3 is a 50% decrease.
