Ok so we have the first portion. We need to do cross multiplication first. So that would be 20(2x - 9) and 10(9)

So
20(2x - 9)=90
40x - 180=90
Then add 180 to itself then to 90
40x=270
X=6.75

Now let’s set the next one up knowing what we know from the previous one.

18(3x + 4)= 12(15)
54x + 72=180
Subtract 72 from it’s self and 180
54x=108
X=2

Work out the area of triangle ABC. B. 25 cm A 32 cm D 2 cm

Law Incorporation [45]

Answer:

Step-by-step explanation:

ΔADB is a right angled triangle. So, use Pythagorean theorem.

Altitude² = hypotenuse² - base²

= (2√5)² - (3√2)²

= 2²* (√5)² - 3²*(√2)² = 4*5 - 9*2 = 20 - 18 = 2

Altitude = √2

Base of ΔABC = 3√2 + √2 = 4√2 cm

Area = $\dfrac{1}{2}bh$

$= \dfrac{1}{2}*4\sqrt{2}*\sqrt{2}\\\\\\=\dfrac{1}{2}*4*\sqrt{2*2}\\\\\\=\dfrac{1}{2}*4*2\\\\= 4 cm^{2}$
