Step-by-step explanation:
8k -2z = 16
to solve for k let's add 2z both sides
8k = 16+2z
divide both sides of the equation by 8
8k/8= 16+2z/8
k= 16+2Z /8
∠1 + ∠3 + 90° = 180°
∠1 + ∠3 = 90°
∠3 = ∠4 (vertically opposite angles)
∠1 + ∠4 = 90°
Therefore, the answer is ∠1 + ∠4
The angles opposite equal sides are also equal. The sum of angles in a triangle is 180. So 2x + 27 + 2x + 27 + 3x + 28 = 180.
7x + 82 = 180
7x = 98
x = 14
Now plug x into each angle to find their measures.
Answer:
5 mph
Step-by-step explanation:
10/2 is 5 miles in one hour.
The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.
