Answer:
A= Q/d +N
Step-by-step explanation:
First you want to move the d term over by dividing both sides
Next you can move the N over by adding it to both sides.
These are complementary angles, meaning they add up to 180
Let's write an equation
180=38 + 42 + (2x+10)
subtract 38 from both sides
142 = 42 + 2x + 10
subtract 42 from both sides
100 = 2x + 10
subtract 10 from both sides
90 = 2x
divide both sides by 2
45 = x
Plug that back into the angle
2x+10
2(45)+ 10
90 + 10
100
The angle is 100 degrees.
To check:
180 =?= 38 + 42 + (2x+10)
180 =?= 38 + 42 + (2(45) + 10)
180 =?= 80 + (90 + 10)
180 =?= 80 + 100
180 = 180
Hope this helps :)
Answer:
3m+4 & m+4+2m
Step-by-step explanation:
substitute m=1
3(1)+4 and (1)+4+2(1)
4+3=7 5+2=7
substitute m=4
3(4)+4 4+4+2(4)
12+4=16 8+8=16
