Answer:
9
Step-by-step explanation:
there are 6 groups of 3 students, that is
number of students = 6 × 3 = 18
They each sell the same number of balloons, thus
= 9 balloons each
Answer:
x=28
Step-by-step explanation:
angle b and angle c are the same measure because it is a iso triangle.
you know triangle sum is 180 so 3x+2(x+20)=180. simplify it to 5x=140
divide both sides by 5
x=28
The area of a rhombus is computed as follows:
A = p*q*1/2
where p and q are the diagonals of the rhombus.
In this case:
A = AC*BD*1/2
A = 6*4*1/2
A = 12 square inches
All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61
Answer:
16
Step-by-step explanation:
the two negatives cancel out so if you are subtracting -8 from 8 you would actually end up adding them.
hope it helps!
