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:
x=4, y=1
I think its that
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
It's 110. Since the one leg is not on zero it's not a full 160 instead you have to subtract 50 where the leg is.
Step-by-step explanation:
13×4/9=52/9
answer as improper fraction is 52/9
Answer:
<h2>
35°</h2>
Step-by-step explanation:
This is an isoceles triangle
And as we all know an isoceles triangle has two equal base angles.
And we also know that the sum of all interior angles of the triangle is 180°
So based on this we can form an algebraic equation of solve for angke t (Let's do it :))
So the base angle is 35°
