Answer:
a. 10
b. -4
Step-by-step explanation:
For these problems, since we are given the x, we plug it into the expression and solve.
a.
3(4)-2 [multiply]
12-2 [subtract]
10
-------------------------------------------------------------------------------------------------------
b.
5(-2)+6 [multiply]
-10+6 [subtract]
-4
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
