Cos x=5/12. Solve for x which is 65.37 degrees.
Answer:
D. 16
Step-by-step explanation:
1. Because these are vertical angles (opposite pair of angles that are formed by intersecting lines), these are congruent. That means (8x-8) = (7x+8).
2. (Solving)
Step 1: Subtract 7x from both sides.
Step 2: Add 8 to both sides.
Step 3: Check if solution is correct.
Therefore, the answer is D. 16.
Answer:
The sum of a° and b° will be 180°.
Step-by-step explanation:
We know that two angles are supplementary when they add up to 180 degrees.
We also know that we know that a straight angle is said to be having 180 degrees. A straight angle does change the direction to point the opposite way.
i.e.
Straight angle = 180°
For example, a flat surface does have an angle of 180 degrees. Also, a straight stick does have a straight angle or 180 degree.
So, from the figure, the sum of a° and b° will be 180° as they add up to 180 degrees on a straight line and hence a° and b° are supplementary angles.
Therefore, the sum of a° and b° will be 180°.
