Answer:
The value of angle α is 18 degree.
Step-by-step explanation:
Given information: Angles α and β are the two acute angles , α < β.
Given equation is
![[\because \sin (90-x)=\cos x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%20%2890-x%29%3D%5Ccos%20x%5D)
Equating both sides.
The value of x is 13.
The measure of angles is
Since 18<72, therefore the value of angle α is 18 degree.
Answer:
14xy/(10x+7y)^
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
In order to calculate this, we simply need to replace the variable c with the value of -8 and solve the inequality.
-9c >= 63
-9 * -8 >= 63
72 >= 63
Since both values are negative the product will be positive. This product is 72 which is in fact greater than 63, thus making the statement True
Put -10 where x is and do the arithmetic.
g(x) = x² + x
g(-10) = (-10)² + (-10) = 100 - 10 = 90 . . . . . . corresponds to selection D
_____
If you like, you can factor the expression to make evaluation easier.
g(x) = x(x +1)
g(-10) = (-10)(-9) = 90
