Question

6. Find the value of angle x in the following triangle.
Hint: Remember that the sum of all angles in a triangle is 180º.
​

Answer 1

Answer:

x+2x+45=180

3x= 135

x= 45

so x= 45 and 2x= 90

Answer 2

Step-by-step explanation:

The sum of triangle is 180°

Let angles of triangle be a,b,c

of 2x,x,45

180= 2x+x+ 45

180-45= 3x

135= 3x

x=135/3

x= 45

a= 2x= 2×45= 90

b= x=45

c= 45

The of sum of this is

90+45+45= 180
