Notice the larger triangle is a right-triangle, and the small one is also a right-triangle. Also notice the "angle tickmark" on each. So both angles have a pair of angles that are equal on each.
the triangles are similar by AA.
Answer:
The rate of discount of a lawnmower is 37,5%
Step-by-step explanation:
Sale price formula is
S = p - rp
where S = sale price,
r = discount percentage rate
p = the original price.
Isolating r
r= (p-S)/p
r= ($168- $105)/$168
r=0.375
r= 37,5%
$403.75
Step 1: 415(.15)
Step 2: 475 - 415(.15)
Step 3: 403.75
Answer:
3.5 units
Step-by-step explanation:
Because ΔPQT is 45-45-90, QT = PQ√2. Therefore, <em>QT is 2</em>.
<em>RS is also 2</em> because all sides of a square are congruent.
Knowing this, we can use the pythagorean theorem to find SU.
<em>RS² + SU² = RU² -> 2² + SU² = 4² -> 4 + SU² = 16 -> SU² = 12</em>
So, SU = √12 ≈ 3.5 units
