Answer:

4.99

Step-by-step explanation:

i cant remember how i got 4.99 but can show u how to check

59.99 divide <u>3</u> = 19.99666667

= 19.99666667 divide 4 (working in reverse as it says 4 times the orig no.)

= 4.99 (was rounded)

An isosceles triangle has 2 angles that measure 37 degrees each. Write 2 different equations that could be solved to find the me
LuckyWell [14K]

Answer:

The third angle of isosceles triangle is 106°   .

Step-by-step explanation:

Given as :

The measures of equal angles of isosceles triangle = 37°

i.e \Theta _1 =  \Theta _2 = 37°

Let The third angle of isosceles triangle =  \Theta _3

Now,

An isosceles triangle is that whose opposite sides are equal and two angles are equal

<u>Now, From the property of Triangle</u>

The sum of all three angles of Triangle = 180°

i.e  \Theta _1 +  \Theta _2 +  \Theta _3 = 180°

∵  \Theta _1 =  \Theta _2 = 37° (given)

So,  37° +  37° +  \Theta _3 = 180°

Or, 74° +  \Theta _3 = 180°

Or,  \Theta _3 = 180° - 74°

∴  \Theta _3 = 106°

So, The third angle of isosceles triangle =  \Theta _3 = 106°

Hence,The third angle of isosceles triangle is 106°   . Answer
