Perpendicular lines gradients times to get -1 so you just use a line with any y intercept but the gradient must times with the gradient you already have to get minus one.

Put each formula in y=mx+b form, then find the inverse of m.
Ex:
1. x+y=2
y=x-2
the inverse of 1 is -1 so the perpendicular line would be y=-x-2

Can someone help me ? Finding angle measures using triangles (veiw image)

adoni [48]

Answer:

x=52°

Step-by-step explanation:

Corresponding angles, 62° is parallel to I

so the letter I would be 62°.

In a triangle there's 180 degrees

so 180-62=118°-66=52°

that way all the angles in the triangle will add up to 180

Find the surface area of the figure

Maurinko [17]

Answer:

Step-by-step explanation:

circumference of cylinder = πd = 5π in

lateral area of cylinder = 5π×9 = 45π in²

Each colored face has a matching face on the other side of the figure.

green areas = 2(17×15) = 510 in²

blue areas = 2(12×17) = 408 in²

gray areas = 2(5×6) = 60 in²

yellow areas = 2(5×12) = 120 in²

red areas = 2(12×15) = 360 in²

total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
