Answer:

1. B. BD

2. C. 15

3. A. 2

Step-by-step explanation:

1. From the figure,

∠DAB = ∠DAC

Therefore, BD is the bisector of ∠ABC.

2. From the figure, IG = GH

3x = 5x - 10

10 = 5x - 3x

2x = 10

x = 5

So, GH = 5x - 10

= 5(5) - 10

= 25 - 10

= 15

Therefore, GH = 15.

3. From the figure,

∠DAB = ∠DAC

10y = 8y + 4

10y - 8y = 4

2y = 4

y = 2

What is the area of the rhombus?

IRINA_888 [86]

The area of rhombus is 24 square units.

Step-by-step explanation:

Given,

Length of one diagonal = p = 3+3 = 6 units

Length of other diagonal = q = 4+4 = 8 units

Area of rhombus = $\frac{pq}{2}$

Area of rhombus = $\frac{6*8}{2}$

Area of rhombus = $\frac{48}{2}$

Area of rhombus = 24 square units

The area of rhombus is 24 square units.
