Answer: 180 is the sum of the tringles

Step-by-step explanation:

2x+7x+11x=180

20x=180

x=9

Now you should put the the value of x to get the angles

2x=2x9=18

7x=7x9=63

11x=11x9=99

Now to double check add all of them together

99+18+63=180

Hoped I helped!

1)V=Ixwxh

=5 cm x 3 cm x 2 cm

=30 cm³

2)V=bxh

=(10m x 6m) x 4m

= 60 m² x4 m

3)V=Ixwxh

=3 cm x 3 cm x 3 cm =27 cm³

=240 m³

<h3>What is algebra?</h3>

Algebra is the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Algebra is divided into different sub-branches such as elementary algebra, advanced algebra, abstract algebra, linear algebra, and commutative algebra.

Elementary algebra: elementary algebra, branch of mathematics that deals with the general properties of numbers and the relations between them. Algebra is fundamental not only to all further mathematics and statistics but to the natural sciences, computer science, economics, and business.

From the given question,

$\sqrt[4]{15^7}$ This expression can also be written in the form of $a^\frac{b}{c}$
