Answer:
-30
Step-by-step explanation:

The value of
.

The value of
is 150°. ✅

We know that,

➡ 81° +
= 180°
➡
= 180° -81°
➡
= 99°
Since an exterior angle of a triangle is equal to the sum of the two opposite interior angles, we have
=
+ 51°
Substituting the value of ''
" in the above equation,
➪
= 99° + 51°
➪
= 150°

<u>Note</u>:-
Kindly refer to the attached file.

All of the statements has the qualifier "can be".
This means that we need just one single in each example to make the statement true.
In an equilateral triangle, medians, angle bisectors, altitudes and perpendicular bisectors are all coincident, which makes the first three statements true. This in turn makes the fourth statement true.
So there are no false statements.
Answer:
8 hours.
Step-by-step explanation:
The pizza house will pay 10 - 6 = 4 dollars in late charges. Each hour costs them 1 dollar. (0.25 per 1/2 hour 0.50 dollars for 1 hour.)
So 1 hour gives a reduction of 0.50 dollars.
x hours gives a reduction of 4 dollars.
0.50 x = 4.00 dollars.
x = 4/0.50
x = 8 hours.
If they keep that up, they will be out of business before too long.
Answer:
V = 24416.6
Step-by-step explanation:
V = 4/3 pi r^3
V = 4/3 (3.14) 18^3
V = 4/3 (3.14) 5832
V = 4/3 (18312.48)
V = 24416.64
