10a) <u>x = 81</u> <u>y = 30.5</u>
Isolate y
2y + 20 = x
2y = x- 20
y = x/2 - 10
Plug in for y
4y - 6 + 64 + x = 180
4(x/2 - 10) - 6 + 64 + x = 180
4x/2 - 40 -6 + 64 + x = 180
4x/2 + 18 = 180
4x/2 = 162
4x = 324
x = 81
Plug in for x
2y + 20 = x
2y + 20 = 81
2y = 61
y = 30.5
10b) <u>x = 47</u>
Isolate x
4x -12 = 3x + 35
x - 12 = 35
x = 47

2. definition of parallelogram
3. < ABD ≅ < BDC
4. < CBD ≅ <BDA
6. I'm not 100% sure what this one is but I think it has something to do with the line of symmetry.
Hope this helps! ;)
Answer:
x= 28°
Step-by-step explanation:
180-118=62
62+90=152
180-152=28
BAM x=28°
<span>Which decimal does not round to 10?
I am not sure but if the teacher allows you to pick more than one choice, circle all because I think none of them is rounded to 10.</span>
Answer:
tan60=p/b
tan60=12/x
x=37.5
now taking sin
sin60=p/h
sin60=12/y
y=(-40) but as length can be negative so
y=40
Answer:Length= 1 foot and 1 inch
Width= 11 inches not sure what it is in feet sorry!
Hope this helps x
