My question.
please Help

Step-by-step explanation:

1. Here we are going to add x plus 54 equalling to 90° as done below

x + 54° = 90°

x+ 54° + 54° = 90° - 54°

x + 0° = 36°

x = 36°

after that we are going to get the value of y

y + 39° = 180°

y + 39°-39° = 180° -39°

y + 0° = 141°

y = 141°

just as we did when getting the value of x

2.here in number 2 we are going to just add

m + 140° + 28° = 360°

m +168° =360°

m +168°-168° = 360°-168°

m +0° = 192°

m = 192°

3. here in Number 3 see below

values of a,b,c and d

value of a

a +50° = 180°

a +50°-50° = 180°-50°

a +0° = 130°

a= 130°

value of b

b = 60° there is no explanation am sorry

value of c

c = 30° no explanation sorry

then the value of d

d + 38° = 90°

d +38°-38°= 90°-38°

d+0° = 52°

d = 52°

hope that will help you

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
