Answer:
let ratio 6:4:2 be 6x,4x and 2x
we have
6x+4x+2x=180 sum of interior angle of the triangle is 180
12x=180
x=180/12=15
Step-by-step explanation:
missing Angle are
6x=6×15=<em><u>9</u></em><em><u>0</u></em><em><u>°</u></em>
4x=4×15=<em><u>6</u></em><em><u>0</u></em><em><u>°</u></em>
2x=2×15=<em><u>3</u></em><em><u>9</u></em><em><u>°</u></em>
First we find out what percent the sale price is of the original price.
0.15 / 0.75 x 100 = 20%
Then we subtract this from 100% to get the discount:
100 - 20 = 80% discount
Answer:
12^2 is 144 and 10^2 is 100 :)
Step-by-step explanation:
12 * 12 = 144
10 * 10 = 100
(2/3)x = 10
(3/2)(2/3)x = 10(3/2)
x = 30/2 = 15
Use the distance formula: d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = 50² + 80²
= 2500 + 6400
= 8900
d = √8900
= 94.3
Answer: 94.3 km
