Answer:
A) 20°
Step-by-step explanation:
Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:


Given statement:

Applying co-function complements

Since, we can represent 70° = 90°-20°
So
Thus,
makes the statement true.
(3,-5)(-8,4)
slope(m) = (4 - (-5) / (-8-3) = (4 + 5) / -11 = -9/11
point slope form : y - y1 = m(x - x1)
there will be 2 answers because there is 2 sets of points
using (3,-5)
y - (-5) = -9/11(x - 3) =
y + 5 = - 9/11(x - 3) <=== here is one
using (-8,4)
y - 4 = -9/11(x - (-8) =
y - 4 = -9/11(x + 8) <== here is the other one
Answer:
x is 48.59
Step-by-step explanation:
sin(x)=0.75------problem
1)you need to get x alone, so inverse
x=sin^-1 (0.75)
2)plug into calculator!
There is you just need to find it
