Answer:
36°
Step-by-step explanation:
Please refer to the attached figure.
Triangles ANC, AMB, BCN, CBM are all isosceles by virtue of the given congruences. By symmetry, we also claim that ΔABC is isosceles (AB≅AC).
We aren't sure how their internal angles relate, but we can write a couple of equations.
Let x = m∠BAC, y = m∠BCN.
∠NCA = ∠NAC = ∠MBA = ∠MAB = x
∠BCM = ∠BMC = x +y
∠BMC = ∠MBA +∠MAB = 2x
So, we have ...
∠BMC = x +y = 2x ⇒ y = x
And the sum of angles around ΔABC is ...
x +(2x) +(2x) = 180°
x = 180°/5 = 36°
The measure of angle BAC is 36°.
Answer: 2, 7, and 3
Step-by-step explanation:
Answer:
A = 5*5=25
P = 5 + 5 + 5 + 5 = 20
Explanation:
If a square has an area of 25 ft then we need to look at the GCF
1,25 5,5 25,1
since it's a square its sides are equal so 5,5 are our length and width.
5 * 5 = 25
the perimeter is all sides added together, so if all sides are equal to 5 the perimiter is
5+5+5+5 = 20
Answer:
I understand your pain
Step-by-step explanation: sadge
The exponential formula for this situtation will be given by:
f(x)=ae^(-bx)
where:
a=initial price
b=rate
x=time in years
hence the formula will be:
f(x)=28750e^(-0.12x)
thus the value of the car in 2018 will be:
x=2018-2012=6 years
thus
f(6)=28750e^(-0.12*6)
f(6)=$13,994.13
