vfiekz [6]
Tinkets:
4x = 30 \\ x = 7.5
now the next step
3x + 4y = 40
since you know x, you're able to substitute

3 \times (7.5) + 4y = 40 \\ 22.5 + 4y = 40 \\ 4y = 17.5 \\ y = 4.375
so trinket: $7.5
doodad: $4.375

What is Perpendicular line?

Two lines that meet or intersect each other at right angles is called a Perpendicular line.

Given that;

TU ⊥ ST

WX ⊥ VW

Now,

When TU ⊥ ST

Then by the image,

∠STU = 90°

When, WX ⟂ VW.

Then by image,

∠VWX = 90°

Hence, The measure of ∠STU = ∠VWX = 90° (right angle)

So, ∠STU ≅ ∠VWX.
