Question

please help I need the answer​

Answer 1

Answer:

first angle = 80

second angle = 25

third angle = 75

Step-by-step explanation:

let the 2 angles measure 1x and 3x

sum of measure of angles of a triangle is equal to 180

therefore, 80+1x+3x = 180

80+4x = 180

4x = 180-80

4x = 100

x = 100/4

x = 25

hope it helps you

Answer 2

Answer:

Let the unknown number be x

so we can write it as

1x +3x =180 - 80 ( 80 is given so it can be subtracted)

4x =100

x=100/4

X is 25

so just put 25 instead of x

1 × 25 is 25

3 ×25 is 75

this is the answer
