b)
Answer:Please give me brainliest
This for the first one
x=5
y=46
z=88
This for second one
x=y
so x=45
y=45
z=11.1
This for the third one
x=60
y=60
z=4.2
This for the fourth one
x=60
y=16
z=16
Step-by-step explanation:
Pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)
Angle 3 is 99 degrees.
Angle 2 is 61 degrees.
angle 1 is also 61 degrees.
