Bro the answer to that is 5
Well it depends on the type of crayon box that she buys. For instance, some crayon boxes have a 24 pack box of crayons while others have 64 or maybe even a 16 pack box of crayons. So it all depends on what kind of box she bought.
12 and 3/8 or if you want it entirely in a fraction 99/8.
Step-by-step explanation:
step 1. make a triangle with the line being the hypotenuse. let a be the base, b the height, and c the hypotenuse.
step 2. a^2 + b^2 = c^2 pythagorean theorem
step 3. 4^2 + 3^2 = c^2
step 4. c^2 = 25
step 5. c = 5 (answer).
Answer:
2.9 units
Step-by-step explanation:
Here the leg lengths are x and 7.7 and the one given angle is 21 degrees.
Think: which trig function incorporates both the length of the side opposite the 21 degree angle (x) and the vertical side (7.7)? It's the tangent function:
tan Ф = opp / adj
To be clear: the side adjacent (next to) the 21 degree angle is 7.7 units in length and the side opposite this angle is x.
Then we have tan 21 degrees = opp / adj = x / 7.7
and so 7.7(tan 21 degrees) = 7.7(03839) = 2.96 or (to one decimal place) 2.9
