Since the triangle is isosceles the measure of angle B is also 47.
since you have dropped a perpendicular bisector the measure of angle x is 90. and since the angles must add to 180 you get 47+47+a=180 and a= 86. since y is half this we have y is 43
if you like my answer please rate as brainliest! thx
The equation is 10 + 2x= 56; 56 - 10= 46; 46 ÷ 2= 23,
The answer is 23 people.
Hope this helps :)
5 3/4 = 23/4.
-4 5/6 = -29/6.
23/4 - (-29/6) = 10 7/12
