Calculate the length of CD if the area of △BCD is 150 cm ²

Mathematics
1 answer:
gizmo_the_mogwai [7]3 years ago
3 0

Answer:

CD = 20 cm

Step-by-step explanation:

Area of Δ = 1/2(Base)(Height)

<u><em>Where Height = 15, Area = 150</em></u>

So,

150 = 1/2(CD)(15)

CD = \frac{150*2}{15}

CD = 10*2

CD = 20 cm

seraphim [82]
4 x³ - 8 x² - 12 x = 
= 4 x ( x² - 2 x - 3 ) =
= 4 x ( x² - 3 x + x - 3 ) =
= 4 x ( x ( x - 3 ) + ( x - 3 ) ) =
= 4 x ( x - 3 ) ( x + 1 )   ( the factored form )

An isosceles triangle has an area of 254 km², and the angle between the two equal sides is 53°. Find the length of the two equal
torisob [31]
Area of a triangle = 1/2 ab sinC

In this equation the angle C is between the two adjacent sides ab
Since the lengths are equal we can call them both X
Hence 254= 1/2 (x)(x) sin53
By simplifying 508 = (x^2) sin53
So therefore x is the square root of 508 divided by sin53 which means the length of the sides is 35.8km to 3 significant figures
