5 Erasers, 4:1 is equal to 20:5, if you just multiply both numbers by 5
Answer:
H. 95°
Step-by-step explanation:
m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°
m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°
The sum of all angles in a placement like this will always equal 360°
So we put all the measures of all angles on one side of thee equation and set it equal to 360*
x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°
After combining like terms we get 9x° + 45° = 360°
After some algebra we get x = 35°
Now at the start we said that m∠DGE is x + 25°
Plug in 35° for x and we get 35° + 25°
The final answer is m∠DGE = 95°
Edit: Sorry if my answer looks a bit confusing. This is actually my first answer on Brainly so I'm quite new to this experience.
Answer:
28 cm
Step-by-step explanation:
The formula for the area of a triangle is 1/2bh
Here we have 1/2 (14)(4)
That comes to 28 cm
You would do 5 x 4 then it will give you 20. after that you will multiply 20 x 1200 and it would give you 24000. (p.s when you multiply 5 x 4 you are finding the # of the boxes
