Answer:
33 degrees
Step-by-step explanation:
(4x+1) and (2x-19) add up to 180 degrees

Answer:
x = 15°
Step-by-step explanation:
7x + 28° = 133° { being vertically opposite angles }
7x = 133° - 28°
7x = 105°
x = 105° / 7
x = 15°
< WPZ = 133° {being vertically opposite angles }
OR
< WPZ = 7x + 28° = 7 * 15 + 28° = 133°
Hope it will help :)❤
1. Answer: D. <span>A = 100 (1/2)^t/13.27
</span>Exponent equation formula would be an= a0( 1+r)^t
In this question, the radio isotopes will become half of its weight after the half-life. So, the ratio would be -0.5 (r= -0.5)
The halftime is 13.27 hours, so the time will be divided by that number. The result would look like this:
an= a0( 1+r)^t
an= a0( 1-0.5)^t/13.27
an= a0( 1/2)^t/13.27
2. Answer: x= 74°
<span>The ladder and the building will make a right triangle with the ladder as the hypotenuse.
The foot of the ladder is 2 feet from the building, so the adjacent side is 2ft.
It reaches a point 7 feet high on the building, so the opposite side is 7ft</span>
You can find the angle by using the tan equation
tan x= opposite / adjacent
tan x= 7/2= 3.5
x= 74°
Answer:
Step-by-step explanation:
Instead, you will use diagrams. To solve such a problem, you must produce a diagram which clearly shows all of the fractions involved in the ... between them have eaten five of the pieces, they have eaten 5/6 of the cake. We also see that ... counting numbers with M<N), then you must show the thing, show it clearly.
