Answer:
Step-by-step explanation:
given :
y = 120 degree
z = 57 degree
angle x = ?
first lets find angle c in triangle BDC
<h3>angle c + z = y (sum of two interior opposite angle is equal to the exterior angle formed)</h3>
angle C + 57 = 120
angle C = 120 -57
angle C = 63 degree
Now lets find angle B in triangle BDC
angle B + angle C + z = 180 degree (sum of interior angles of a triangle)
angle B + 63 + 57 = 180
angle B + 120 = 180
angle B = 180 - 120
angle B = 60 degree
now for angle x
angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)
60 + 57 = x
117 = x
Answer:
add the faces and bases
Step-by-step explanation:
2(.5×12×16)+(10×16)+(10×12)+(20×10)
Answer:
if you mean like 14/3. you would divide 14 by 3 which would give you 4 times which would equal 12 so you would have two left over that couldn't be divided by 4 and you have to keep the three so the answer would be 4 2/3. with 4 being the big number and 2/3 being the other half of the mixed fraction
