Answer:
Step-by-step explanation:
Arithmetic sequence formula:
, where a is the term, n is the position of the term, and d is the common difference between the terms.
Plug in values:
Solve:
Definition of tangent of a given angle α :
tan( α ) = measure of the opposite side / measure of the adjacent side.
For the given case,
angle α = 35 °
measure of opposite side = x cm
measure of adjacent side = 12 cm
From definition of tangent,
tan(35 ° ) = x/12
Isolate and solve for x:
x=12 tan(35) = 12 * 0.7002 = 8.4 cm
Answer:
C
Step-by-step explanation:
5+2y+3z=5+3z+2yA
Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.
5+3z+2yA=5+2y+3z
Resta 5 en los dos lados.
3z+2yA=5+2y+3z−5
Resta 5 de 5 para obtener 0.
3z+2yA=2y+3z
Resta 3z en los dos lados.
2yA=2y+3z−3z
Combina 3z y −3z para obtener 0.
2yA=2y
Anula 2 en ambos lados.
yA=y
Divide los dos lados por y.
y
yA
=
y
y
Al dividir por y, se deshace la multiplicación por y.
A=
y
y
Divide y por y.
A=1
