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.

40 POINTS Geometry homework

kicyunya [14]

$\angle{DBC }$ =(5x+4)°

$\angle{ A }$ =(2x-2)°

$\angle{C }$ =(4x-6)°

we know that,

$\angle{DBC}$ = $\angle{A}$ + $\angle{C}$

According to the question,

$\tt{ 5x+4=2x-2+4x-6 }$

$\tt{ 5x+4=6x-8 }$

$\tt{ 6x-5x=4+8 }$

$\blue{x=12 }$

so,

$\angle{C }$ =(4x-6)°=(4×12-6)°=(48-6)°=42°
