All the angles in a triangle equal 180 degrees.
So,
y+40+y+30= 180
2y+70= 180
2y= 110
Divide by 2.
y= 55
"A" is the answer.
I hope this helps!

The answer is 22 cupcakes.
I just subtracted 8 out of all the answer choices until I was left with 1 (the leftover cupcake). 22-8-8=6 and you can't subtract 8 out of 6 and get 1 so it can't be the number of cupcakes baked on that day
Answer:
P(B and V)=10%
Step-by-step explanation:To solve this poroblema we use the formula of combinations:
C(n,r)=(nr)=n!(r!(n−r)!)
Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:
5C2=
5C2=10
The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:
2C2=1
Then the probability is:
P( B and V)=
=0.1= 10%

Answer:
Step-by-step explanation:
The perimeter of ABCD is 30cm
The Sum of the perimeter of three rectangles at the corner is 20cm.
following the variables as the same as you assigned
large rectangle: u by v
rectangle center A: 2a by 2b
rectangle center B: 2c by 2d
rectangle center D: 2e by 2f
2 equations (from the givens):
2u+2v=30
2(a + b + c + d + e + f )= 20
now to find the length
a+b+a/2+b/2+(v-b/2-d/2)+c/2+d+c+d/2+(u-c/2)+(v-f/2)+e/2+f+e+f/2+(u-e/2-a/2)
which is (a+b+c+d+e+f)+u+v+u+v = 10+30=40
