8/9 * 1/4 = 8/36 division of fractions is equal to the multiplication of the reciprocal
Answer:
31 degrees
Step-by-step explanation:
well each three point of a triangle equals 180
so 20+35= 55 180-55= 125
now if the exterior angle is 156 and it should equal 180 the interior angle would be 24 degrees
now we have 24 and 125 so angle ? = 31
Answer:
y should be 5, when u solve for the angles u get 68+87+c=180, if c is y^2 then y is 5
