Use the triangle pictured to calculate the following measurements.
DanielleElmas [232]
Perimeter:
 The perimeter of the triangle is the sum of its sides.
 We have then:
 P = 8 + 12 + 10
 P = 30 units

 Semi-perimeter: 
 In geometry, the semiperimeter of a polygon is half its perimeter.
 s = P / 2
 s = 30/2
 s = 15 units.

 Area: 
 Knowing the semiperimeter and the sides, the area is:
 A = root (s * (s-a) * (s-b) * (s-c))
 where,
 s: semi-meter
 a, b, c are sides.
 A = root (15 * (15-8) * (15-12) * (15-10))
 A = 39.68626967
 A = 40 units ^ 2

PLEASE HELP!!! WITH #’S 12,20,21
Lisa [10]

12 should be 25% just divide 10 by 40 which gives you .25 then multiply by 100 and that gives you 25%

20 should be 33.33& divide 7 by 21 that gives you .3333 muliply by 100 that gives you 33.33%

21 should be 7.5 since you multiply the percent by the whole to get the part which would be .15 multiply by 50 which is 7.5

Very much struggling with geometry right now, would appreciate the help ❤️
ELEN [110]

Answer: x= 30

Step-by-step explanation:

These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x
