Answer:
13 degrees
Step-by-step explanation:
Let x be the degree measure of the angle's complement
Then we have the other angle is x + 64
Because the 2 angles complement each other so the sum of the 2 angles is 90
So we have the equation: 2x + 64 = 90
<=> 2x = 26
<=> x = 13
90^2+120^2=c^2
180+240=c^2
420=c^2
2 radical 105
Answer:
12.25%.
explanation :
I add 8.25% and 4 since you are trying to find the interest of his account earn after 4 years. 8.25 + 4= 12.25. Yea so that is how I get my answer.
Answer:
Para simplificar cualquier expresión algebraica, las siguientes son las reglas y pasos básicos: Elimine cualquier símbolo de agrupación, como corchetes y paréntesis, multiplicando factores. Usa la regla del exponente para eliminar la agrupación si los términos contienen exponentes. Combina los términos semejantes mediante suma o resta.
Remember
all angles add to 180
x+y+z=180
one is 2 times as another
x=2y
measure of 3rd angle (z) is 20 more than smalllest
since y has to be doubled to get x, y is smallest
z is 20 more than y
z=20+y
we have
x=2y
z=20+y
sub those
x+y+z=180
2y+y+20+y=180
4y+20=180
minus 20 both sides
4y=160
divide 4
y=40
sub back
x=2y
x=2(40)
x=80
z=20+y
z=20+40
z=60
the angles are
80 degrees, 40 degrees, 60 degrees
