Answer:
Step-by-step explanation:
Common denominator: 18
-14/18 + 11/18
= -3/18
Reduce:
-1/6
29
1. plug in -10 for x
-2(-10) + 9
2. multiply -2 x -10 = 20
20 + 9
3. add 20 + 9 = 29
true
the steps won't be the same
∠CAB = 33 {alternate interior angles}
5x = 33 + 2x { exterior angle equals sum of opposite interior angles}
5x - 2x = 33
3x = 33
x = 33/3
x = 11
∠B = 2x = 2* 11 = 22
∠ECB = 5x = 5*11 = 55
now that we know how long each one is, let's plug those in Heron's Area formula.
