<u>Explanation</u><u>:</u>
Consider ABCD is a rhombus
We know that
All sides are equal in rhombus i.e,
⇛AB=BC=CD=DA
and AC and BD are digonals
Given that
Diagonal and the side of the rhombus are equal.
⇛AB = BC = CD = DA = AC
Diagonal AC divides the rhombus into two triangles .
They are ∆ BAC and ∆ DAC
In triangle BAC
BA=BC=AC,(Given)
⇛∠ BAC=∠ABC= ∠ACB =60°→→→Eqn(i)
Similarly in ∆DAC ,
DA=DC=AC
⇛∠DAC=∠ACD=∠ADC=60°→→→Eqn(ii)
From eqn(i) and eqn(ii)
∠A=∠BAC+∠DAC=60°+60°=120°
and
∠B= ∠ABC = 60°.
and
∠C=∠ACB+∠ACD=60°+60°=120°
and
∠D =∠ADC=60°
∴ ∠A = 120° , ∠B = 60° ,∠C = 120° & ∠D = 60°
<u>Answer:</u><u>-</u>The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°.

Answer:
Step-by-step explanation:
Isolate the variable by doing operations to both sides of the equation.
The work is shown below:
Answer:
A
Step-by-step explanation:
From the diagram, angle A is congruent to angle E. This is because they are both marked with the same symbol, signifying that they are congruent.
Answer:
6 3/4
Step-by-step explanation:
3/4 * 9 = 27/4
How many times does 4 go into 27
It goes in 6 times (4*6 = 24) with 3 left over
The left over part goes over the denominator
6 3/4
