Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = \frac{1}{2} × (Base) × (perpendicular height)

Area = \frac{1}{2} × (10) × (3)

Area = \frac{30}{2}

Area = 15 cm²

So, final answer is 15 cm².

Find y using Pythagorean theorem or proportion
Tcecarenko [31]

We have three similar triangles, let's see if we can get this right, right vertex first, then other vertex from small side:

EDF ~ GDE ~ GEF

As ratios that means

ED:DF:EF = GD:DE:GE = GE:EF:GF

x:20:y = 5:x:GE = GE:y:15

Since we're after y we choose

20/y = y/15

20(15) = y²

y² = 300

y = 10√3

y ≈ 17.32

alexis rode her bike 4.5 miles. johnny rode his bike 8.1 miles. how many more miles did johnny ride his bike?
Ahat [919]
Hey there!

The key word in there is Many more. Whenever you see that word, it usually means to subtract

So you would subtract 4.5 from 8.1
8.1
-4.5= 3.6
