Answer:
BC = 1.71
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
α = 70°
a: adjacent = BC
h: hypotenuse = 5
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
we look at which meets those data between the sine, cosine and tangent
is the cosine
cos α = a/h
Now we replace the values and solve
cos 70 = a/5
0.34202 = a/5
0.34202 * 5 = a
1.7101 = a
round to the neares hundredth
a = 1.7101 = 1.71
BC = 1.71
Answer:
The quandrants on a grap are basically the groups on the graph like quadrant I ,II ,III , and IV hope that helps
Step-by-step explanation:
According to the 72 rule
72/rate=time
72÷9.6=7.5 years
Another way to solve by using the main equation
2300=1150(1+0.096/4)^4t
Solve for t
t=((log(2,300÷1,150)÷log(1+(0.096÷4))÷4))=7.31years
Hope it helps :-)
15^2 + 20^2
= 225 + 400
= 625
square root of 625 = 25
answer:<span>length of the Hypotenuse is</span> 25
Answer: 30 degrees
Step-by-step explanation:
Corresponding angles of similar triangles are congruent.
