When adding 10 to any two digit number, increase the left digit by 1. For example 20+10= 30. 55+10=65. If a problem says 10+ (a number), you can reverse the order the numbers are in because of the commutative property of addition. Example: 10+50 eqauls 50+10. Both equations equal 60. Also, Rodney would have 39 pieces of fruit since 20+19 is 39.

It depends. Multiples of 10 are:
10, 20, 30, 40, 50...........
And a 2 digit number can be anything between 10 and 99.

To comment: Rodney would have 39 pieces of fruit.

Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D

Ivahew [28]

Check the picture below.

$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D$

$\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D$
