I thought of a two-digit number. The unit digit of my number is 7 more than the tens digit cubed. What is my number?

18.

Step-by-step explanation:

If the tens digit is x^3 the unit digit is x^3 + 7

So 10 * x^3 + x^3 + 7 < 100    (as its a 2 digit number).

11x^3 < 93

x^3 < 8 5/11

x <  2.04

As x must be an integer it is either 1 or 2.

It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.

The answer is 1  and (1+7)  = 18.

It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.  

The answer is 1  and (1+7)  = 18.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
