Answer:
x = 7deg
Step-by-step explanation:
7x + 10 + 15x + 16 = 180 (angles adjacent to each other in a //polygon are supplementary)
22x = 154
x = 7deg
This is a question on polygons and angles. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
2(5x+4)+3(2x-1)
Use the distributive property for both sets of parenthesis:
2(5x+4) = 2*5x + 2*4 = 10x+8
3(2x-1) = 3*2x - 3*1 = 6x-3
Now you have:
10x+8 + 6x-3
Now combine like terms:
10x + 6x = 16x
8-3 = 5
The final answer is 16x+5
