Find the value of x easy math question #3 please help

x =8

Step-by-step explanation:

-12 + 9x = 60 (the other angles are 60, 180 - (60 + 60) = 60)

9x = 72

x = 8

x = 8°

Step-by-step explanation:

We know that sum of interior angles of a triangle is 180°, therefore;

(Angle 1) + (Angle 2) + (Angle 3) = 180°

(60)° + (60)° + (-12 + 9x)° = 180°

120° + (-12 + 9x) = 180°

108° + 9x° = 180°

9x = 180 - 108

9x = 72°

x = 72/9

x = 8°

Therefore the value of x is 8°.

Hope this helps!

answer: 15

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
