Question

please tell me full statements please ​

Answer 1

Answer:

1, seven

2,obtuse angle

3,180 degree

Answer 2

Answer:

1. 5cm ,2. 19° ,3. 60°

Step-by-step explanation:

1. let the hypotenuse be x

by using Pythagoras theorem

hypotenuse^2=perpendicular^2+base^2

x^2 =4^2+3^2

x^2 = 16+9=25

x = √25=5cm

2. the sum of supplementary angles is 180°

let the second angle be x

161+x = 180

x = 180-161

x = 19°

3. sum of all angles of triangle is 180°

in equilateral triangle all angles are equal

let the measure of angles be x

x+x+x =180

3x = 180

x =180/3

x =60°
