Answer: Deena is correct
Step-by-step explanation:
Deena is correct because the number doesn't terminate nor does it repeat. If it does not repeat or terminate it means it is irrational.
Divide 12 by 1.5 so you have a number you can directly multiple with 40.
12/1.5 = 8
The multiple 8 by 40 to get the number of miles.
8(40) = 320
<span>length of the side = 1.2 / 4 = 0.3 m
area = 0.3</span>² = 0.09 m²

⤻ Before solving the given question , you should know the answer of these questions :
✺How do you find the hypotenuse , perpendicular and base when the angle (
) is given ?
⇾ The longest side , which is the opposite side of right angle is the hypotenuse ( h ). There are two other sides , the opposite and the adjacent. The naming of these sides depends upon which angle is involved. The opposite is the side opposite the angle involved and it is called the perpendicular ( p ) . The adjacent us the side next to the angle involved ( buy not the hypotenuse ) and it is called the base ( b ).
☄ 
In the above cases ,
is taken as the angle of reference.
♪ Our Q/A part ends up here! Let's start solving the question :
❈ 
- Perpendicular ( p ) = ? , Hypotenuse ( h ) = 18 & base ( b ) = 16
✧ 
- Value of tan

✎ 
Firstly , Finding the value of perpendicular ( p ) using Pythagoras theorem :
❃
[ Pythagoras theorem ]







Okey, We found out the perpendicular i.e
. Now , We know :

Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees
hope this helped
