Consider ABCD is a rhombus
We know that
All sides are equal in rhombus
=> 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°………(1)
Similarly in ∆DAC ,
DA=DC=AC
=><DAC=<ACD=<ADC=60°……….(2)
From (1) and (2)
<A=<BAC+< DAC=60°+60°=120°
and
< B= < ABC = 60°.
and
<C=<ACB+<ACD=60°+60°=120°
and
< D =<ADC=60°
Therefore, <A = 120° , <B = 60° ,<C = 120° ,<D = 60°
<u>Answer:-</u>
The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°
<u>Used formulae:-</u>
all sides in a rhombus are equal
Simplify the second equation.
1/2y = -x + 1
Multiply both sides by 2
y = -2x + 2
Since both equations equal y you can set them equal to each other.
-2x + 2 = 3x - 1
Solve for X
-5x = -3
x = 3/5
Plug this into one of the equations.
3(3/5) - 1 = y
1.8 - 1 = y
y = .8
(0.6, 0.8)
A
No 9 is bigger than the other 2 added together.
B
3+ 6 = 9. A triangle cannot be formed.
C
4+5 = 9. A triangle cannot be formed. The shorter two will just make the length of the longest side. No triangle made.
D
Yes 4+6 > 9 A triangle will be formed.
E
Yes 5 + 5 = 10 which is greater than 9. A triangle will be formed.
Answer:
$705.79
Step-by-step explanation:
(see attached for reference)
the formula for compound interest is
A = P [1 + (r/n) ]^(nt)
Where:
P = Principal Amount = $500
r = annual interest rate = 9% = 0.09
t = 4 years
n = 1 (compounded annually)
A = 500 [1 + (0.09/1) ]^(1 x 4)
A = 500 [1 + 0.09 ]^(4)
A = 500 [1.09 ]^(4)
A = $705.79
Answer:
solve for x first and then y
Step-by-step explanation:
once you know what x is than y , ur answer will equall out
