Find ∠C and hence classify each triangle according to:

a. the number of equal sides it has, and

b. the type of angles it has, e. g. equilateral triangle & acute-angled

triangle.

Given Angles ∠C Number of equal

sides

Types of Triangle

∠A = 20

∠B = 60

a) 0

b) scalene and obtuse

Step-by-step explanation:

∠A = 20

∠B = 60

∠C = 180 - 20 - 60 = 100 (obtuse)

Since none of the angles are equal, no sides are equal either

So, it's a scalene triangle

Since one angle is obtuse, it's an obtuse triangle

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
