Answer:
36 and 48 and 96
Step-by-step explanation:
add 3+4+8=15
all of the angles in a triangle have to add up to 180
so 180÷15=12
now for this ratio, each part will equal 12
so we have to multiply each of the parts by 12
3×12=36
4×12=48
8×12=96
those are the measures of the angles
you can add them up again and see that they equal 180
you can try dividing and you will see that they also equal the ratio
Answer:300,000
Step-by-step explanation: if the 4 was a 5 or higher then the answer would’ve been 400,00 but since the number next to the underlined digit is 4 then it goes to 300,00. (4 or below leave it alone 5 or above give it a shove)
The formula of an area of a circle:
r - a radius
We have r = 14m. Substitute:
If you want an approximate area, you can accept 
Then:
Answer:
18x+21
Step-by-step explanation:
First multiply each equation by 2 since there is 2 sides for both the length and width.
2(2x+3) 2(7x+9)
4x+3 14x+18
Then combine like terms
4x+14x 3+18
18x 21
