Question

find the unknown lettered angel ​

Answer 1

Answer:

2x+3x+90° = 180°

5x = 180-90

5x = 90

x = 90/5

x = 18

2x = 2×18 = 36°

3x = 3×18 = 54°

Answer 2

Answer:

Value of 3×=54

Value of 2×=36

Step-by-step explanation:

Sum of the sides of a triangle =180°

Angle given =90°

Unknown angles =2x and 3x

To find the x we must set up an equation which would be =

3x+2x+90=180

Now let's solve it=

5x+90=180

5x=180-90

5x=90

90÷5

18

Now we will multiply 18 by

3 and 2

18×3=54

18×2=36
