Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:
The sum of all angles in a quadrilateral = 360°.
Therefore,
Solve for x
The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
I believe that the answer is 1/5 but i am not entirely sure
Answer:
B.
Step-by-step explanation:
On our left, we have 7 "x's" and 7 "1's". Let this be 7x + 7.
On our right, we have 5 "x's" and 16 "1's". Let this be 5x + 16.
We would have the equation:
Solve for x. Collect like terms.
Divide both sides by 2
4 × n = 4n
anything to ask please pm me
p= popcorn
x=number of kids in class
c= cost
Plug in data:
c = px
31.5=1.5x
Divide both sides by 1.5:
21= x
There are 21 kids in the class.
