Answer:
x = 11
Step-by-step explanation:
∠BCE + ∠ECF = 180°
∴(10x + 15)° + 5x° = 180°
(15x + 15)° = 180°
15x = 180° - 15°
15x = 165°
x = 165°/15°
x = 11°
Answer: 153
Explanation: Supplementary angles mean two angles that add up to 180 degrees. So all you have to do is 180-27 and you get 153.
ANSWER
Find out the how many cans does each one have.
To proof
As given
Amelia and Elliott are collecting empty soda cans for recycling
Amelia has 13 less than 5 times the cans that Elliott has.
let us assume that the Elliott has can be =x
Amelia can = 5x -13
Total can = 257 cans
than the equation becomes
x + 5x - 13 = 257
6x = 257 +13
6x = 270
x = 45
Elliott has can be = 45cans
Amelia can = 5 × 45 - 13
= 212cans
Hence proved
Answer:
Scalene acute
Step-by-step explanation:
All angles measures are less than 90 so it would be acute. No sides are equal so it would be scalene
