Answer:
<em><u>x = 60 </u></em>
Step-by-step explanation:
<em>So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.</em>
180 - 109 = 71
<em>After that you have to add what you already have (49 degrees) with what you just found (71 degrees)</em>
49 + 71 = 120
<em>Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it. </em>
180 - 120 = 60
Twelve(multiplied) by four to the (power) of 2
Start by distributing
30x - 300 = 15x
add 300 to both sides
30x = 300 + 15x
subtract 15x from both sides
15x = 300
divide both side by 15
x = 20
the answer is 6(2) - 2(4) + 5
answer: 9
