Answer:
9
Step-by-step explanation:
6.4(x)+2.8y=44.4
6.4(3)+2.8y=44.4
19.2+2.8y=44.4
2.8y=25.2
y=9
Answer:
m<R ≈ 22.62°
Step-by-step explanation:
Reference angle = R
Side opposite to R = 5 cm
Adjacent side length = 12 cm
Thus, applying TOA, we have:
Tan R = opp/adj
Tan R = 5/12
R = tan^{-1}(5/12)
R ≈ 22.62° (nearest hundredth)
Answer:
x=13 degrees
Step-by-step explanation:
First, think of the remote interior angle theorem. So basically the remote interior angles that don't share a vertex with the exterior angle is the sum of the exterior angle. So that means ∠EBC+∠BEC=∠ECD. ∠ECD=64 degrees+90 degrees=154 degrees. ∠EBC is equal to 180 degrees minus 3x because line AD is a line so ∠ABE and ∠EBC are supplementary angles so basically they add up to 180 degrees. So the equation is (180-3x)+x=154. Simplify the equation and you should get x=13 degrees:)

Answer:
Step-by-step explanation:
The expression to simplify in this problem is
Which can be rewritten as
Or also as
Now we can apply the following rule for the calculation of the power of a power:
So we get:
Which can therefore be rewritten as
And so, we get
which can be finally rewritten as
